Print a phone case, sure. Print a desk organizer, fine. But print a scooter, one with wheels, brakes, a motor, and enough structural gumption to carry an actual adult human being down a street, and you have crossed into a different category of insane entirely. Ivan Miranda crossed that line without blinking, treating a 3D printer less like a hobbyist gadget and more like a small scale factory capable of manufacturing an entire vehicle from the ground up.
What makes it properly deranged is not just that the scooter exists. It is that the scooter fits in a suitcase. Every panel, every bracket, every printed part was designed to break down small enough to check onto a flight, then get reassembled on the other side into a machine that actually rides, brakes, and turns corners like it means it. Somewhere over Europe on the way to Prague, there was a scooter sitting quietly in cargo, waiting to become a scooter again the moment it landed.
Designer: Ivan Miranda
Miranda started by building his rims out of repurposed lawn mower tires, which are naturally too flat sided for anything that needs to lean into a corner. His fix was to print the rims narrower than usual, so the two internal rings sit closer together, which stops the tire sidewalls from bowing outward once inflated. The result rounds over just enough to behave like an actual motorbike tire rather than a garden tool accessory. It is a small trick, but it is the kind of trick that separates a scooter that rides from one that just sits there looking like a scooter.
Power comes from two 36 volt tool batteries wired into a belt driven hub motor, stepped down through a DC to DC converter to run the lights and horn at 12 volts. An Arduino handles the accelerator signal, translated from a modified potentiometer hidden inside the right handlebar. The one part Miranda refused to trust to plastic was the front fork shaft, which carries the combined forces of his body weight, the bike’s size, and the stresses of actual riding. That piece was machined in aluminum instead, a rare concession from a builder otherwise committed to printing nearly everything else on the machine.
The kickstand uses a bi-stable mechanism, a bearing riding over a cam bump that snaps it firmly into either the stored or deployed position without any wobble. The seat, printed in flexible filament, sits on a hinge that doubles as hidden storage underneath. Braking comes from a modified bicycle disc setup, with the disc’s center hole enlarged to accept a printed axle, and the caliper mounted loosely enough to self-align during use. None of it reads like a shortcut. All of it reads like someone who genuinely enjoys solving problems most people would rather buy a solution for.
The whole point of the build was travel, and it delivered. Miranda flew the disassembled scooter to Maker Faire Prague, packed into an ordinary suitcase, and reassembled it on site well enough to win the event’s suitcase sized project contest. Hackaday picked up the story shortly after, noting that what Miranda calls a motorbike looks, by most definitions, closer to a scooter, a distinction that promptly spiraled into a comment section argument about vehicle taxonomy nobody asked for. The finished machine weighs a little over 14 kilograms without its batteries, light enough to make the whole suitcase premise plausible rather than theoretical.
Miranda has since gone back and refined the design, swapping more of the metal components for printed equivalents and simplifying the hardware for anyone determined to attempt their own build. The updated files are now sold through his site, complete with a bill of materials and a heavy dose of legal disclaimers reminding buyers this is a hobby project, not a certified vehicle. Whether anyone else actually manages to pull a working scooter out of a suitcase remains to be seen, but the fact that Miranda proved it possible at all says something about where 3D printing has quietly ended up.
What would it look like for a building material to behave more like a living organism? Rameshwari Jonnalagedda has been sitting with that question, and Minimal Matter is her answer in clay. Drawing on the mathematics of minimal surfaces, geometries that appear in soap films, leaf veins, and cellular membranes, she has developed a system of 3D-printed terracotta forms that adapt to context the way natural structures adapt to environment. Each piece is porous and open-ended, capable of functioning as a thermal surface, an ecological habitat, or a structural element depending on how its geometry is tuned. The work is produced through additive manufacturing, which allows for continuous variation without additional cost or complexity. The forms look ancient and computational at once, as though the earth had been asked to solve an equation and answered in terracotta.
Jonnalagedda frames the work as a framework rather than a product, a set of conditions from which form continues to emerge long after the printer has stopped. The structures are designed to host moss, insects, air, and light, becoming more themselves over time rather than less. There is something almost philosophical in that proposition, the idea that a designed object could have an open-ended future, that it might weather and colonize and shift rather than degrade. Most materials we build with are fighting time. Minimal Matter is cooperating with it.
I keep thinking about the Sagrada Família when I look at these pieces, which is admittedly a strange place for the brain to go when confronted with palm-sized terracotta modules. But Gaudí spent his life studying natural load-bearing geometries, catenaries and paraboloids and hyperboloids, and insisting that nature had already solved the structural problems architects were torturing themselves over. Jonnalagedda is working in a completely different register, scale-wise and ambition-wise, but the underlying conviction is the same. The math is already there. Your job is to listen to it.
What makes Minimal Matter visually arresting, beyond the obvious formal beauty of the pieces, is the way the layering from the 3D printing process becomes part of the surface language. Close up, each form reads almost like topographic contour lines, the deposit of clay recording every decision the algorithm made. You can see the logic of the geometry in the material itself, which is rare. Most 3D-printed objects try to hide their process, with sanding, acetone baths, or even tweaking the build settings to reduce ‘steps’ from showing. These celebrate it, and the terracotta’s warm ochre tone makes the whole thing feel less like a prototype and more like something excavated.
Individual pieces stack, combine, and reconfigure, which means the system scales without losing coherence. A single module functions as a sculptural object on a desk. Four stacked become a column. Spread flat across a surface, they start to read as landscape. This scalar flexibility is genuinely hard to achieve in material design, and Jonnalagedda pulls it off by keeping the underlying geometry consistent while varying the expression at the surface level.
The work points somewhere larger than a single award category can contain. Jonnalagedda is asking a question that the construction industry has been too busy pouring concrete to consider: what if the things we build were grown into place rather than imposed upon a site? What if a wall could host an ecosystem, a surface could regulate temperature through its own geometry, a material could become more itself the longer it was left alone? Minimal Matter, recognized in the Young Talents category at the Design Intelligence Award, doesn’t answer all of those questions, and it doesn’t need to. It just makes them impossible to ignore.
Concrete is everywhere. It’s in the walls you’re staring at right now, the floors under your feet, the skyline you pass every morning on your commute. It’s the most widely used construction material in the world, and it’s also one of the most environmentally damaging ones we have. Cement production alone is responsible for roughly 8% of global CO2 emissions, a figure that tends to get quietly buried under louder conversations about cars and plastic straws. That imbalance has always struck me as odd, and worth talking about more.
So when a team of six researchers and designers from the Technion, Israel Institute of Technology, presented CyanoCement to the world, it stopped me mid-scroll. Not because it felt like a minor improvement on what already existed. Because it framed the problem differently. It asked whether a building material could do something more than just cause less harm, whether it could actually participate in solving the problem it had always been part of.
CyanoCement is a 3D-printable biocement made with cyanobacteria, tiny photosynthetic microbes that have been around for billions of years. They’re among the organisms responsible for producing Earth’s first oxygen-rich atmosphere. That’s not a throwaway fact. These are ancient, extraordinary little things, and the Technion team, Perla Armaly, Yuval Berger, Lubov Iliassafov, Keren Rosenblau, Yechezkel Kashi, and Shany Barath, figured out how to make them a functional part of the construction process.
Here’s the mechanism: the cyanobacteria use photosynthesis to bind minerals and precipitate calcium carbonate, forming a solid material without any of the high-heat, high-emissions processes that traditional cement requires. The part that genuinely surprised me was that the material doesn’t stop capturing CO₂ once production is done. It continues to pull carbon from the air after it’s been formed and installed. Not just a lower-impact alternative to concrete, but a material that actively works against the problem.
The team designed it specifically for non-load-bearing architectural elements, facades, interior panels, decorative structures, which keeps the project grounded and credible. I respect that kind of restraint. The sustainable design space has a well-documented tendency to oversell, to position a concept-stage material as a revolution before the science has caught up. CyanoCement doesn’t do that. It knows what it is right now, and what it is right now is genuinely impressive.
Then there’s the color. The material is green, not because of any coating or pigment, but because of the living organisms inside it. That green is a biological signal, a visual confirmation that the cyanobacteria are alive and active. I’ve seen a lot of sustainable products that ask you to trust the environmental benefit, buried somewhere in a lifecycle assessment document. CyanoCement makes it visible. The building itself tells you it’s working. That’s both smart design and, I’d argue, a kind of integrity.
The project came out of the Disrupt Design Lab at Technion’s Faculty of Architecture and Town Planning, developed in collaboration with the Applied Genomics Lab at the Faculty of Biotechnology and Food Engineering. Architecture and biology don’t typically share a lab, let alone a design philosophy. The fact that this team brought those two disciplines together into something coherent, functional, and visually compelling is its own accomplishment, separate from the material itself.
CyanoCement was recognized by the Green Product Award, which has a strong track record of identifying work that actually moves the needle rather than just speaking well in press releases. The project earned that recognition, not just for good intentions, but for the depth of research behind it and the clarity of its design logic. The more you learn about how it works, the more convinced you become.
We talk a lot about the future of architecture being green, solar panels on rooftops, recycled steel, passive ventilation. All worthwhile. But CyanoCement is asking something a little more radical: what if the walls themselves were alive? What if building something meant contributing to the atmosphere rather than depleting it? That’s the question I can’t stop thinking about. And once you know it’s being asked, I suspect you won’t be able to stop either.
3D printing is redefining the language of future technology and design. Tech peripherals are evolving from standardized, mass-market products into sculpted forms. This transformation signals a tectonic shift – where precision fabrication meets individuality, and performance aligns seamlessly with form.
For designers and conscious consumers alike, 3D printing enables precise ergonomics, material efficiency, and expressive geometry to coexist seamlessly. The result goes beyond customization, fostering a new ecosystem of tools that respect sensory feedback and minimize waste. It transforms everyday technology into a refined, human-centered design experience across industries ranging from consumer electronics and gaming to wearable tech and medical innovation.
1. Computer Peripheral Tectonics
The workstation now operates as a micro-architectural environment where precision, materiality, and human anatomy converge. Through 3D printing, the computer peripheral is redefined from a standardized accessory into a deliberately engineered component. Mice, keyboards, and input tools become tectonic objects that are formed with structural clarity and material authenticity, responding directly to natural hand geometry and movement patterns rather than generic manufacturing molds.
This transformation delivers tangible ergonomic advantages by minimizing repetitive strain through proportionate scaling and calibrated spatial alignment. As design thinking evolves, customized printed interfaces are recognized for enhancing workflow efficiency and sensory engagement. Tactile feedback becomes integrated into the rhythm of work, elevating everyday digital interaction into a more intuitive, refined, and human-centered experience.
This mouse – Whaley is not just a character but a fully realized product shaped through iteration and hands-on experimentation. What began as a simple whale sketch evolved into a compact wireless mouse designed to balance personality with practicality. The form is sculpted to sit naturally under your palm, with the whale’s rounded back supporting the hand instead of mimicking a generic plastic shell. Its head integrates the left and right click buttons, while the scroll wheel is positioned like a subtle blowhole, blending function seamlessly into form.
The body went through multiple 3D-printed prototypes, refining the curve of the spine, the flexibility of the click panels, and the fit around the internal components. Electronics from a standard wireless mouse were carefully transplanted into a custom shell, ensuring reliable tracking and smooth scrolling.
2. Sculpted Gaming Interfaces
In the gaming sphere, 3D printing unlocks sculptural freedom that reshapes standard controllers into precision-engineered ergonomic forms. Instead of uniform plastic casings, high-performance shells are built with intricate lattice geometries that reduce weight while maintaining structural rigidity. This layered construction improves airflow, supports thermal regulation during extended sessions, and enhances overall durability.
Beyond function, the aesthetic impact is equally transformative. Integrated LEDs diffused through translucent printed lattices create atmospheric depth and spatial glow. The controller becomes immersive architecture in hand and less of a mechanical device and more a responsive extension of the player’s digital identity, blending sensory engagement with advanced fabrication technology.
GamiFries is a purpose-built 3D-printed accessory designed exclusively for the Nintendo Switch 2. It functions as a clip-on fries holder that attaches directly to the console using its built-in magnetic system, locking into place with a clean, secure snap. The structure is engineered to remain stable in both handheld and docked modes, ensuring it does not interfere with gameplay, button access, or screen visibility. Its lightweight printed body keeps the added load manageable while maintaining balance during extended play sessions.
The container replicates the familiar silhouette and ridged texture of a classic McDonald’s fries pack, but its proportions are optimized to sit flush against the console. Fasteners and adapters are integrated into the design for a firm hold, and minor magnetic polarity issues can be corrected through simple recalibration.
3. High Performance Audio Form
3D printing has transformed high-fidelity audio by enabling complex internal geometries that traditional milling or casting cannot achieve. Speakers can now be fabricated with non-parallel internal walls and intricate chamber structures that reduce standing waves and distortion. This precision engineering refines acoustic clarity, allowing subtle tonal details and dynamic range to emerge with greater authenticity. The enclosure becomes a structurally intentional form where material integrity and acoustic science operate in alignment.
Beyond performance, these printed speakers contribute to a curated sensory environment. Their sculptural exteriors reflect the logic of their internal acoustic architecture, creating harmony between sound, space, and visual form—an immersive experience where engineering meets poetic design.
The Anomalo FM Radio by SHINKOGEISHA is designed as a functional object that challenges conventional radio aesthetics. Instead of a compact rectangular body, it features a vertical antenna that acts as the structural spine. From this central axis, multiple colorful limbs extend outward, each assigned a specific function. The form is intentionally exposed, turning mechanical and electronic components into visible design elements rather than concealing them within a casing.
Each protruding branch operates as part of a three-dimensional control system. A roulette-style dial enables station tuning, a cylindrical red knob adjusts volume, and a bold yellow speaker projects sound. Another module houses the batteries, while visible wiring connects the components, reinforcing the radio’s engineered transparency. Manufactured using digital fabrication techniques and PLA material, the device prioritizes structural experimentation and modular assembly.
4. Wearable Organic Interface
Wearable technology represents the most intimate intersection between body and device, and 3D printing refines that relationship with anatomical precision. Through detailed body scanning, smart glasses, health monitors, and adaptive bands are fabricated to align perfectly with individual contours. This tailored construction enhances long-term comfort, reduces material waste, and streamlines production. Instead of standardized sizing, the device responds directly to human geometry, delivering structural clarity and material efficiency in equal measure.
Experientially, these wearables are designed to feel almost imperceptible. Their lightweight calibration and ergonomic balance allow them to integrate naturally into daily movement. Personalization also improves sensor stability and data accuracy, elevating performance outcomes. The result is technology that moves beyond utility, becoming a refined extension of the body rather than an external attachment.
Researchers at the Universities of Gothenburg and Isfahan have developed a revolutionary 3D-printed helmet built with auxetic metastructures that react dynamically to collisions. Unlike traditional foam liners that simply compress, these geometric patterns pull inward on impact, dispersing energy more efficiently. The protective layer is made from a hyperelastic polymer that stretches and returns to its original form, allowing the helmet to maintain performance even after repeated impacts. Standardized crash tests showed significantly improved protection compared to conventional foam designs.
Beyond performance, customization sets this innovation apart. Traditional helmets come in fixed sizes and often fail to match individual head shapes perfectly, reducing both comfort and safety. With 3D printing, the auxetic liner can be tailored precisely to the rider, creating a snug, gap-free fit. Although currently more expensive, advancing technology is expected to lower production costs. This breakthrough could soon redefine not only cycling helmets but protective gear across multiple industries.
5. Personalized Medical Engineering
In the medical field, 3D printing enables the creation of patient-specific devices that traditional manufacturing cannot achieve. Custom orthotics, prosthetic limbs, and surgical guides are fabricated based on detailed anatomical scans, ensuring exact alignment with the patient’s body. This precision reduces discomfort, improves functionality, and accelerates recovery. Instead of standardized solutions, each piece is engineered as a structurally intentional form that responds directly to individual physiology.
Beyond fit, the technology enhances clinical performance. Lightweight lattice structures improve breathability and reduce material use, while rapid prototyping shortens production timelines. The outcome is a highly responsive healthcare ecosystem where design intelligence, structural clarity, and human well-being converge in measurable and transformative ways.
Bracesys by the Osteoid Design Team rethinks fracture immobilization as a precision-engineered, adjustable system rather than a static cast. Instead of plaster or rigid prefab braces, it uses a lightweight segmented framework weighing just 150 grams. The structure folds flat into an envelope for storage, then expands into a rigid wrist support comparable to traditional casting. Articulating connectors and calibrated tension dials allow clinicians to shape the brace directly on the patient’s limb, adjusting fit instantly and refining compression as swelling reduces during recovery.
Kevlar cables run through the frame and tighten through integrated dials, distributing force evenly across the structure for controlled stabilization. The body is produced using SLS and MJF 3D printing in medical-grade Nylon 12, reinforced with CNC-machined aluminum and stainless steel at high-stress points. Data from over 600 CT scans informed four optimized sizes that cover most wrist anatomies while maintaining semi-custom adaptability. Spring-loaded quick-release pins simplify adjustments, and individual components can be replaced when needed. Reusable, recyclable, and mechanically precise, Bracesys shifts immobilization from fixed fabrication to real-time clinical customization.
3D printing is steadily transforming the way products are imagined and made. Across industries, it enables smarter structures, efficient material use, and greater design freedom. By allowing form and function to evolve together, this technology supports more adaptable, thoughtful solutions. The future of design is becoming more responsive, refined, and human-centered through additive manufacturing.
Something significant happened in Bezannes, France — and the construction industry should be paying close attention. ViliaSprint², Europe’s largest 3D-printed apartment building, has been completed, and it arrives less as a proof of concept and more as a genuine blueprint for what housing could look like moving forward. Developed by Plurial Novilia, designed by HOBO Architecture, and printed by PERI 3D Construction using a COBOD BOD2 printer, this is the kind of project that makes you reconsider what a building even is.
The numbers are striking. Twelve social housing apartments across three floors, 800 square meters of living space — all printed on-site in just 34 days, down from an originally planned 50. That alone would be a headline. But what makes ViliaSprint² genuinely remarkable is that it’s the first building in France where both the load-bearing structure and every wall were printed directly on-site, with 100% of all loads transferred through the 3D-printed walls. No hybrid workarounds. No conventional skeleton hiding beneath the surface. The printer did the heavy lifting, quite literally.
HOBO Architecture’s design leans into the honesty of the medium. The building’s rounded geometry — fluid curves that would cost a fortune to achieve through conventional formwork — is made possible precisely because a machine, not a tradesperson, is doing the forming. It’s design that could only exist with this technology, which is a rarer claim than it sounds. Timber balcony structures offset the weight of the concrete shell, adding warmth to a building that could otherwise read as cold and industrial.
Sustainability is baked into the structure rather than retrofitted onto it. The optimized curved form saved roughly 10% of concrete volume. Holcim supplied the printable concrete using its TectorPrint technology within the CO₂-reduced ECOPact range, reinforced with synthetic macro fibres. Perlite insulation, 500 square meters of photovoltaic panels, and a hybrid gas-heat pump system by Atlantic Systèmes push the building to around 60% energy self-sufficiency — fully compliant with France’s RE2020 2025 green building targets.
The building sits directly beside a conventionally constructed twin, built by the same developer simultaneously, as a live comparison. The 3D-printed version finished three months ahead. It also required only three workers to erect the walls, compared to six for the conventional build — a meaningful detail as the construction industry faces deepening skilled labor shortages.
Plurial Novilia is already planning the next move: roughly 40 apartments, two printers running simultaneously, with a target to cut print time by a factor of four. ViliaSprint² isn’t the destination. It’s the proof that the destination is real.
Most conversations about technology and craft follow the same script. Technology is fast, scalable, cold. Craft is slow, precious, warm. The two might share a showroom floor or a mood board, but they rarely share a philosophy. Mahdi Naïm’s AERIS bicycle saddle disagrees with that entire premise, and the disagreement is worth paying attention to.
AERIS is not a bicycle saddle that happens to look interesting. It is a bicycle saddle built around a single, demanding question: what if 3D printing and traditional craft weren’t layered on top of each other, but designed together from the very first sketch? That shift in thinking, from assembly to co-authorship, is what separates AERIS from the dozen other “tech meets heritage” products that surface at design fairs every season.
Designer: Mahdi Naim
The structure is built on a lattice produced through high-precision photopolymerization, specifically SLA and DLP printing, in high-performance elastomer resin. The geometry is not decorative. It is functional in the most literal sense: the lattice density changes across three zones of the saddle, denser where firm support is needed under an aerodynamic riding position, progressively softer through the transition zone, and open at the perineal relief zone to minimize pressure. No foam. No padding added to compensate for poor design thinking. The structure itself is the comfort system.
That kind of discipline is rare, and I say that as someone who has watched a lot of product design lean on material additions to solve problems that should have been solved earlier. Foam is easy. Getting the geometry right from the start is not. It takes conviction to design without a fallback.
The second layer, and I do mean the second design logic rather than a second material slapped on afterward, is where a French master saddler comes in. Full-grain vegetable-tanned leather, hand-stitched. The studio is clear that this is not an aesthetic decision. The leather works mechanically with the resin, distributing pressure and shear forces in ways that neither foam nor synthetic materials can match at equivalent weight. The interface between the two materials was designed during the modelling phase, not decided once the print came out of the machine.
This is the part I keep coming back to. The leather isn’t a finish. It isn’t branding. It is the second structural argument in the same conversation, and the conversation started before any material was touched. That level of intentionality is genuinely unusual, even among products that wear the word “craft” proudly on their labels.
Mahdi Naïm himself is worth knowing, if you don’t already. He is an industrial designer, a Grand Maître Artisan, and a German Design Award laureate who runs his studio between Lyon and Casablanca. His practice sits at the intersection of French engineering and Moroccan craftsmanship, and AERIS reads like a project that could only come from someone fluent in both languages. The saddle doesn’t feel like a technology demonstration with craft applied on top, or a heritage object with a 3D-printed frame underneath. It feels like one object, made by two disciplines that had to agree on every decision before anything was built.
AERIS is still in active development and moving toward small-series production. The studio is in conversation with industrial partners in additive manufacturing and premium cycling. That means this isn’t a concept in the gallery-piece sense, displayed under glass and admired from a distance. It is a product that intends to be ridden.
Whether you cycle or not, whether you follow product design closely or just occasionally land on something that makes you stop scrolling, AERIS is the kind of object that rewards a second look. Not because it is visually striking, though it is, but because the thinking behind it is genuinely coherent. The lattice, the leather, the hand-stitching, the parametric modelling: none of it is decoration. All of it is argument. That is harder to pull off than it looks, and considerably rarer than the design world likes to admit.
The first time I looked at the Flow Chair, I thought it was a sculpture. The sinuous, looping form bending into itself like a standing wave frozen mid-motion. No visible joints, no screws, no padding, no legs in the traditional sense. Just one continuous ribbon of material that somehow, impossibly, holds a person’s weight while gently rocking beneath them.
That last part surprised me. The Flow Chair, designed by Daniel Streilein and Henry Boy of the German studio Boldobjects, is not actually a chair in the way we typically think about chairs. It’s a rocking stool, and it functions through the intelligence of its shape rather than through any kind of mechanism. You shift your weight, and it responds. You lean forward to concentrate, and it follows. You settle back, and it adjusts. No moving parts. No knobs to turn. No assembly required. The geometry does all the work.
Designers: Daniel Streilein and Henry Boy (Boldobjects)
I’ve been thinking about this a lot lately, specifically the idea that so much of modern ergonomic furniture design has overcomplicated the act of sitting. We’ve added lumbar supports and pneumatic height adjustors and tilt-tension knobs, and yet most office workers still end the day with a stiff back and a neck that sounds like a bowl of cereal. The Flow Chair is a direct argument against all of that. Its proposition is simple: give the body room to move, and it will figure out the rest.
The manufacturing process is just as interesting as the design itself. The Flow Chair is produced using large-scale pellet 3D printing, a more industrial cousin of the desktop 3D printing most people are familiar with. This process allows for the kind of fluid, organic geometry that would be nearly impossible, and almost certainly cost-prohibitive, to achieve through traditional molding or casting. You can actually see the layer lines running across the surface of the chair, horizontal bands that trace the path of the print head as it built the form up from nothing. Most designers would treat those lines as a flaw. Streilein and Boy treat them as texture, a visual record of how the object came to be. I find that genuinely compelling. The chair doesn’t hide what it is.
What makes the sustainability story here worth paying attention to is that it isn’t just a marketing footnote. The Flow Chair is made from a single material: recycled PETG. No adhesives, no hardware, no secondary components of any kind. When the stool eventually reaches the end of its life, it can go back into the production cycle without complex processing. The branding is embossed directly into the base material rather than applied as a separate label. Even the decision to manufacture locally in Germany shortens the supply chain in a meaningful way. Every design choice reinforces the same intention, and that kind of coherence is rarer than it should be.
It also comes in a range of colors including deep forest green, powder blue, sage, and near-black, which tells you something about how Boldobjects is thinking about this object. It’s not purely a functional tool. It’s a considered, designerly thing meant to live in real spaces with real aesthetics. Looking at the photographs, it holds its own in a warm, book-lined study just as well as it does in an eclectic living room. That versatility is harder to engineer than it looks.
The Flow Chair sits, if you’ll allow the pun, at an interesting intersection. It belongs in a conversation about sustainable materials and digital fabrication, yes, but it also belongs in a conversation about what good design actually feels like to live with. Not just to look at. Not just to Instagram. To actually use, day after day, in the small and ordinary act of sitting down. That turns out to be a higher bar than most furniture ever clears.
Forget the $800 Scandinavian pet cave or the linen-covered cube that your cat ignores in favor of your laptop bag. The most genuinely entertaining piece of pet furniture to cross my feed this year is a 3D-printed house shaped like a vintage CRT television, and the entire joke is that your pet becomes the programming. You sit on the couch. You watch the TV. The TV contains a cat. This is better than anything currently streaming. Designer burnski uploaded the STL pack to Cults3D in January, and the community has been printing it in color combinations ranging from dark grey with cyan accents to warm brown with blush pink ever since, each build landing in someone’s living room like the world’s most wholesome conversation piece.
The file set runs to 39 components, assembles with a dry-fit connector system and superglue, and requires a print bed of at least 240 x 240 x 240mm to pull off at full scale. The form is pitch-perfect: four tapered legs, two ball-tipped rabbit-ear antennas, three knurled channel knobs, a honeycomb speaker grille, and a wide rounded-rectangle screen opening that your cat, dog, or rabbit walks through and promptly falls asleep inside. Community makes already show cats curled up in the screen cavity like they are the most relaxed broadcast in television history, which, honestly, they are.
The design language burnski landed on is pure 1960s broadcast era, the kind of chunky, corner-rounded CRT silhouette that populated every American living room before flatscreens made televisions invisible. That specific form carries enormous nostalgic weight right now, showing up on tote bags, neon signs, and enamel pins everywhere you look, but burnski is one of the few people who has taken it somewhere genuinely functional. The rounded body, the splayed legs, the antennas, none of these are decorative afterthoughts. They are load-bearing elements of a visual joke that only works if every detail commits. A CRT pet house with stubby legs and no antennas is just a box with a hole in it. This one reads as a television from across the room, which is the whole point.
Thirty-nine individual STL files cover every component from the outer casing panels, split into eight sections labeled 1A through 2D for assembly sequencing, to the antenna mounting blocks, the knob faces, and the front and rear ventilation grilles. The connector system is built directly into the parts, so the dry-fit assembly process is essentially self-guiding before you reach for the superglue. Burnski recommends two or three filament colors, minimum two walls, and ten percent infill for most structural components, with support material only required under the monitor section. The rear ventilation panels and front grille inlays get a special tip in the build notes: flatten them in your slicer, zero out the top and bottom layers, and the exposed infill pattern becomes a design feature. Community makers have used gyroid and honeycomb infill patterns to striking effect on these panels, visible in the finished build photos circulating on Cults3D.
Given the fact that you’re 3D printing this, you can choose from a variety of colors. The grey-and-cyan version that burnski’s own build photos show is clean and almost graphic, the kind of colorway that would not look out of place in a design-forward apartment. However, you aren’t limited to that – go wild with pastels or neons, or just stick to a single-color print if you’re constrained by filaments and then paint designs/patterns onto it later. It’s ultimately a pet-house, so remember to use paints that are safe and non-toxic.
You can play around with scale to make sure the shelter fits your pet. At 1:1 scale, a full-grown cat fits inside the screen cavity with room to curl up comfortably, which means the assembled unit is genuinely substantial, closer in presence to a bedside table than to a desktop decorative object. That scale is also what makes the living-room-television joke land in person rather than just in photographs. A miniature version would be cute if you own a tinier pet. A version large enough for an actual animal to live inside, sitting on four legs at floor level while you watch it from the couch, is something else entirely.
The STL pack is available on Cults3D for $2.84 USD, making it one of the more absurdly good-value design files on the platform relative to what you actually get. The print time is substantial, the assembly requires patience, and you will need superglue and a printer with a fairly large print-bed if you’re going to print this thing at scale… but the community make photos tell the real story here: people are finishing this build, dropping it in their living rooms, and watching their pets walk straight in and claim it. The channel is always on. The programming never disappoints.
Most desk organizers solve a problem and stop there. They hold your pens, keep your paper clips from migrating, and that’s the entire story. Ikigaiform’s Aya & Sfera collection has a different agenda entirely. These small, 3D-printed cups manage to hold your belongings while looking like they were pulled from a gallery shelf, and the story behind how they got there is just as interesting as the objects themselves.
Ikigaiform describes their work as “Japanese minimalism meets parametric design,” and that phrase does a lot of heavy lifting. The studio creates objects that feel simultaneously ancient and futuristic, with a restraint to the forms, a quietness, but also a kind of visual complexity that rewards closer attention. Wabi-sabi aesthetics and Japandi sensibility run through everything they make, and Aya & Sfera is no exception. These are objects designed for calm spaces, and you can feel that intention even in the photographs.
What makes this collection particularly clever is where it came from. Aya and Sfera didn’t start as desk organizers. They began as full-size self-watering planters, part of Ikigaiform’s celebrated collection of organic-form pots with intricate surface patterns. The demand was apparently loud enough that the studio took those same exact geometries and scaled them down into compact cups, sized just right for a desk or bathroom shelf. The result is that your pen holder and your planter can share the same DNA, the same design language, the same almost-living quality.
The Aya series draws its form from the twisting structure of Banisteriopsis caapi, a vine with a natural spiral growth pattern that creates a sense of continuous motion. The left and right twist variants in the Yagé pattern look like they’re caught mid-rotation, as if the object is slowly unwinding if you watch it long enough. The Sfera series takes a different route, with Ondula wave patterns and a Pinecone texture that plays beautifully with light along its ridged surface. Both series also introduce Meandro, a brand-new S-curve surface pattern making its debut here. Ikigaiform mentioned it had been in development for a while and they waited for the right moment. I think the timing works.
What I appreciate about this collection is that it refuses the idea of a hierarchy between decor and function. A pen holder has always felt like the kind of object you apologize for, something utilitarian and forgettable stuck in a corner of your desk that you only notice when it tips over. But these cups occupy the same visual space as a ceramic vase or a sculptural piece you’d actually seek out. They make you want to rearrange your entire workspace around them.
The fact that all files are free on MakerWorld is worth pausing on. Ikigaiform offers everything in both STL and 3MF formats, with print settings already baked into the file. No supports are required, and while the profiles are pre-configured for Bambu Lab printers, any FDM machine handles these geometries without issue. Each plate includes three cups so you can print the full set in one go, or individual plates if you only want one. At approximately 100mm by 110mm, they’re compact without feeling small.
The maker community’s response says a lot. Since dropping on MakerWorld in March, the collection has racked up thousands of boosts and prints, with people using them for exactly what you’d expect: pens, toothbrushes, markers, random desk things. But plenty of people are also printing them purely as decorative objects, with no functional intention at all. I find that telling. When someone prints something they don’t functionally need and displays it anyway because it looks good, the design has absolutely done its job.
The broader 3D printing world is still shaking off its reputation for producing chunky, plasticky objects that shout “I made this at home.” Aya & Sfera quietly push back on that. They’re proof that parametric design, handled with restraint and a clear aesthetic point of view, can produce objects that belong on any shelf, printed or otherwise.
Every time you type a prompt into ChatGPT, something happens somewhere far away. Servers spin up. Electricity moves. Carbon gets generated. The whole transaction is so clean and invisible on your end that it might as well not be happening. That’s by design, and it’s worth thinking about. Although with the way we use technology these days, we seldom think about the consequences on our environment.
London-based creative studio Oio wants to change that, starting with a small 3D-printed box and a bright yellow pinwheel. Their project, the Hot Air Factory, is a domestic AI device that processes your questions and requests locally, without connecting to the cloud, and every time it thinks, it physically exhales. Hot air pushes out of the top of the device and spins that cheerful little pinwheel. The harder it thinks, the faster it spins. You’re watching computation happen in real time, which turns out to be a surprisingly powerful thing.
The concept is simple: make the invisible visible. We know AI uses energy. We’ve read the headlines. But knowing abstractly that data centers are energy-hungry is different from watching a pinwheel turn every time you ask your AI assistant to summarize something. One is a statistic. The other is a moment of honest accountability.
What makes the Hot Air Factory smart, beyond its obvious design appeal, is how it translates cost into human-readable terms. It doesn’t give you kilowatt-hours because most people have no idea what that means. Instead, it tells you something like “that prompt cost the equivalent of brewing a cup of tea” or “watching Netflix for five minutes.” Suddenly the math becomes personal. Suddenly you start wondering whether you really needed a 500-word AI response to a question you could have Googled.
Oio co-founder Matteo Loglio describes it as “a small, domestic AI that reveals the hidden energy cost behind every prompt.” The factory also lets you dial up or down the level of intelligence it uses. Want a quick answer? Use a lighter model, spend less energy. Need something more complex? Crank it up, and watch that pinwheel work for it. You can even schedule your heavier prompts for the night shift, when energy is cleaner and the grid is quieter. These are design decisions that carry real ethical weight, and they’re baked in with zero condescension.
The playfulness and the seriousness aren’t in conflict here. They’re exactly the point. The Hot Air Factory is built in a Frutiger Aero visual language, all soft curves and clean optimism, the kind of aesthetic that makes you want to put it on a shelf next to your plants. But underneath that approachable exterior is a genuinely complicated machine running open-source large language models on a local GPU. It looks like something a friendly robot would carry. It functions like a small act of protest.
AI companies have very little incentive to make their energy costs legible to users. Invisibility is convenient. It keeps things frictionless. It keeps you prompting without thinking about the bill. A report from the US Department of Energy projected that by 2028, data centers could account for 12% of total electricity consumed in the US. That’s not a small number, and it keeps growing every time we treat AI like it runs on good intentions and cloud magic.
The Hot Air Factory isn’t saying AI is bad. It isn’t demanding you stop using it. What it’s doing is quieter and more persuasive than that. It’s asking you to look. To see. To feel, just a little, what your digital habits cost in the physical world. That’s the argument made not through a lecture or a campaign, but through a yellow pinwheel spinning in your living room.
Design can do that. Sometimes a small, well-made object says more than a policy paper ever could. The Hot Air Factory is currently looking for collaborators to help bring it to a wider audience, still working its way from experiment to something anyone can own. If the goal is conscious computing, the first step might just be this: a tiny box, a spinning fan, and the quiet discomfort of watching a machine breathe.
