Somewhere between a Samsung phone that wobbles on every flat surface and a lawn sprinkler that immediately drenched everything within a two-metre radius, Mrwhosetheboss set himself a mission: test the most popular 3D prints on the internet, climbing from just over a thousand downloads all the way to the single most downloaded project of all time, to find out what a 3D printer can actually do in the real world. What started as a curiosity turned into a reckoning with how much ordinary stuff people buy without realising they could just print it. The answer, it turns out, is an unsettling amount.
From a wobbly Samsung to a sofa drink tray that actually works
The climb starts at roughly 1,000 downloads with a Samsung phone case fitted with an anti-wobble pin. The fix is so small it barely qualifies as engineering, yet it solves the kind of daily frustration that makes you briefly hate an expensive device. Score: 7 out of 10. At 2,000 downloads, a shower amplifier props a smartphone inside a glass cradle over the shower screen and redirects the sound so directly it feels, by his own account, like wearing a pair of earphones. The only flaw: a 40-minute unskippable ad mid-shower. Seven.
An AirPods dock held by a strip of double-sided tape charges the case via USB-C while keeping the earbuds instantly grabbable. Pulling the whole unit off the wall, he noted, looks like ‘the world’s most useless panic button.’ Ten out of ten. The 3,000-download phone stand for watching in bed holds a 45-degree angle that looks wrong until you are actually lying down, at which point it feels exactly right. The crocodile bag clip at the 5,000 mark earned a rare zero-notes rating: the hinge holds at any angle, the snap is deeply satisfying, and the crocodile shape is simply a bonus.
The sofa arm tray, printed in wood filament to match the furniture, slides into the gap between cushions with enough friction to stay flat. The drink stays level because the tray is angled to offset the sofa’s natural downward slope. Nine out of ten, and he left it there permanently.
The prints that made him question every purchase he has ever made
The sharpest moment in the whole exercise came when he realised a wrist rest he had been recommending to friends at $25 a unit can be printed for less than a hundredth of that price. ‘It doesn’t quite have the same soft touch finish,’ he admitted, ‘but it’s still 100% better than not having anything at all.’ Eight out of ten.
A 12,000-download lamp called the Wave required only a separately purchased LED strip costing around 8 pounds. The printed shade distributes light across its curves in a way he could not find a single point of criticism for. Ten. The video game storage chest, with locking trays printed specifically for Game Boy Advance, Nintendo Switch, and PS5 cartridges, earned an eight. A Harry Potter bookend that wraps the first book around a printed Harry figure took, by his estimate, ‘a proper 30 seconds to figure out what’s going on.’
The 3D printed slippers, made from a softer TPU material certified for skin contact, were the clearest proof-of-concept in the whole run. ‘They have just the right amount of squid that I was looking for,’ he said, landing on ten out of ten. The Connect 4 set, modified to use spheres instead of coins, sorts every ball perfectly into its own coloured half when the game ends, meaning the loser no longer has to do what he called ‘the cleanup of shame.’ Also a ten.
At the top of the download chart, with 415,000 downloads on Maker World and more across other platforms, sits a small boat called Benchy. It does not hold anything. It does not fix anything. It floats upside down. It exists purely as a calibration benchmark, packed with arches, overhangs, and underside text that only resolve cleanly on a properly tuned printer. The single most downloaded 3D print of all time is, by design, completely useless.
A cat named Milo, rendered in blended color
After working through dozens of existing designs, he dropped a photograph of his late cat Milo into a generative tool that stripped the background and reconstructed the fur strand by strand as a 3D model. The printer blended colors from already-loaded filaments as it went, mixing shades across the coat without requiring a separate spool for each tone. The finished piece caught the light reflection in Milo’s eyes. He gave it an eight, then paused, and added: ‘Sorry.’
The sofa tray is still there, holding a drink at the correct angle, in a house that now has about 40 more drawers left to organize.
