Mrwhosetheboss Rated the Internet’s Most Popular 3D Prints. The Most Downloaded One Is Useless.
Mrwhosetheboss just spent a video 3D printing the internet’s most popular downloads, from barely discovered models all the way up to the single most downloaded print of all time, and scoring each one out of 10. The punchline arrives at the very end: the most downloaded print on the planet doesn’t do anything at all. The good stuff sits in the middle, and one of the best is a wood-grain sofa tray that takes about 16 hours to print.
The video, “I Tested the Most Downloaded 3D Printed Tech!”, went up on November 4 and passed 2 million views within its first day. It’s sponsored by Bambu Lab, and every model came from Bambu’s MakerWorld library and was printed on its machines. Keep that in mind when he gets excited about the hardware.
The 16-hour sofa tray earned a 9
The problem it fixes will be familiar to anyone with a big couch. Seats at the ends get an armrest for drinks. Everyone in the middle gets nothing. The Sofa Tray (v2) with cupholders by LAYR Studio slides into the gap between seat cushions and holds two drinks.
He was impressed by two details. It grips the cushions with enough friction to stay put, and the surface is angled to cancel out the natural downward slope of the seat, so the drink sits level. He printed it in wood filament to match the room and said he was happy to leave it there for good. Score: 9 out of 10.
It isn’t a quick print, though. The model’s main profile on MakerWorld lists a print time of 15.6 hours, which matches the roughly 16 hours of printer time this one took.
Every score he gave
He worked roughly in order of downloads, from around 1,000 up to Benchy’s 415,000 on MakerWorld. These are the prints he gave an actual number on camera:
| What it does | Score | |
|---|---|---|
| Mechanical Under-Desk Charging Dock | Hides and charges AirPods Pro 3 under a desk | 10 |
| The Wave Design Lamp | Designer-style lamp (LED bought separately, about £8) | 10 |
| Air Slides | Soft printed sliders | 10 |
| Cascade Connect | Connect 4 with balls that sort themselves after the game | 10 |
| Easy Release Clothes Hanger | Squeeze to release a shirt without stretching it | 9.5 |
| Sofa Tray (v2) with cupholders | Drink holder that wedges between sofa cushions | 9 |
| Ultimate Game Cartridge Storage Chest | Locking chest with trays for GBA, Switch and PS5 games | 8 |
| Sliding Wrist Rest Support | Mouse wrist rest, close to a $25 one he already owns | 8 |
| Large Trash Can with Lid | Self-closing bin | 8 |
| Beyblade Kit Card | Whole spinning top and launcher in one print | 8 |
| Image-to-3D model of his cat, Milo (MakerLab) | Photo turned into a color-mixed print | 8 |
| Samsung S26 Ultra HEX Case | Case with a pin that stops the camera-bump wobble | 7 |
| Shower Speaker Amplifier | Phone holder that boosts sound in the shower | 7 |
| BreezeBuddy Max | Hand-crank fan (a bit loud) | 7 |
| Instax Mini Photo Rolodex | Flip-through photo display (fiddly frames) | 6 |
| Portable Chair with Suitcase Function | Briefcase that unfolds into a chair | 6 |
| Card Shuffler | Mechanical card shuffler | 6 |
| Bicycle Gyro Can Holder | Gimbal cup holder for a bike | 3 |
A few prints got verdicts instead of numbers. The Crazy Crocodile Clip was “the best bag clip I’ve ever used.” He loved the Harry Potter bookend, was clearly delighted that the airless basketball actually bounces, and called Gridfinity, the modular drawer organizer at nearly 100,000 downloads, “art.” The Zelda ocarina is playable, but not exactly pleasant to listen to.
The most downloaded print of all time is a tiny boat
At the top of the chart is Benchy, with 415,000 downloads on MakerWorld alone. It’s a little boat that holds nothing and fixes nothing. People print it because it’s a calibration test. The overhangs, arches and tiny text on its hull only come out right if your printer is dialed in, so it’s become the first thing almost everyone prints. His verdict: the most popular 3D print of all time is “completely useless.”
That breaks the theory he started with, that more downloads would mean better prints. The four 10s and the sofa tray all sit in the long middle of the download chart.
The sponsor part: Bambu Lab’s H3C
The later prints show off Bambu Lab’s newly announced H3C. In the video it has nine toolheads with filament preloaded and preheated, swaps colors or materials in about six seconds instead of 14 or more, and can mix colors as it prints. It’s also what printed the sliders, in a softer TPU that Bambu says is certified for skin contact. Those are the sponsor’s claims as presented in a paid video, not something we’ve tested, so wait for independent reviews before treating them as settled.
Want to print these yourself?
You don’t need the brand-new H3C, which we couldn’t find on Amazon yet. Bambu Lab sells its current printers through its official Amazon store, and any of these can handle the single-color prints above:
- Bambu Lab A1 Mini Combo: the compact starter, with AMS lite for multicolor. Check the build size first, because the larger prints, like the sofa tray, may need a bigger bed.
- Bambu Lab A1: the full-size open-frame option, with room for bigger prints.
- Bambu Lab P1S Combo: enclosed, faster, and comes with the AMS for multicolor and more materials.

PCGeek’s take
Ignore the download counts when you pick your first prints. The most popular file is a test, and the best ones in this video solve one small, specific problem in your own home: the cable under your desk, the drink in the middle of the couch, the hoodie stuck on a hanger. Most of these don’t need a nine-head flagship either. The sofa tray, hanger and crocodile clip are single-color prints any decent printer can handle. You just have to be willing to let one run overnight and then some.
Which of these would you actually print first, and what’s the most useful thing you’ve ever printed? Tell us in the comments.
