There are COOL keychains, and there are CUSTOM keychains. We've done you a solid and compiled a list of COOL CUSTOM keychains to 3D print.
Ah, the humble keychain. It’s capable of more than just holding your keys, y’know. Much more.
Thanks to the creative possibilities of 3D printing — and the endless generosity of the maker community — there’s a steady torrent of cool custom keychains to 3D print.
The benefits are that these models are small and easy to fabricate. That means production time is short, and the filament use on a fused deposition modelling (FDM) machine is economical.
But they are also eminently practical, and a feat of engineering prowess in miniature form. So whether you’re looking for a survival whistle, or a pocket torch, or a bottle opener, you’re bound to find something useful in the list below.
Did we miss any of your favorite designs? Let us know in the comments, and we’ll consider them for a future update.
As everybody knows, a slice of hot pizza is best enjoyed with a cold bottle of beer. This charming design from 3D Brooklyn combines the two motifs into a funky keychain, complete with pepperoni and cheese topping. There’s scope also to provide multiple colors to each layer of “topping”, you simply pause at the right moment and swap out the filament. The leverage is provided by single penny, which is inserted after the model is printed.
When watching video on a smartphone on the move, propping it up with a stand is very useful. It leaves you hands-free to gobble popcorn, knit a sweater, or pick your nose. You can make these cool custom keychains in three different designs — a dragon, a slug or a hippo — and it’s recommended that you use flexible filament for added durability. It´s made by Shira.
The V29 is a LOUD whistle which is 100% guaranteed to shake your windowpanes. Why is it called the V29? Because the designer actually tested 28 different variations before settling on this version. It’s strong and tough (it can survive being dinged into the pavement, for example), and it has a secure loop for a key ring. Take one along, because you never know when you might need it. Cool custom keychains can be life-savers, too. It´s made by Joe Zisa.
The strong flex door carabiner is a very popular model to 3D print, and justifiably so. It’s a quick and easy model to fabricate, but also very well designed and eminently useful. Not sturdy enough to carry your weight by any means, but certainly useful for latching onto keys and bags. As cool custom keychains go, this one’s an absolute winner. It´s made by ddf3d .com.
At first glance, this model looks like an innocuous kitty charm. Awwwww, look at the pointy ears! But where danger lurks, this kitty can show its claws. Place two fingers in the eye-sockets and use it as a defensive tool; the two prongs are sharp enough to deter would-be attackers. These cool custom keychains also have a heartwarming backstory — the designer made it at the request of his dear mother. It´s made by Brandon Watt.
If you have more than one set of keys in your household, then it certainly helps to keep them properly organized. The wall-mounted Prism does exactly that, where a little triangular dongle on a key ring slots neatly into a larger grid of triangles. Color-code each dongle with different filaments, and you’ll have a neat visual cue of precisely what belongs where. It´s made by thomas raygasse.
When doing a big shop for the weekly groceries, it’s something of a pain if you don’t have correct change for the trolley. Remedy a first-world problem with a first-class solution; a 3D printed shopping cart token. Of course, it means that your cool custom keychains will be dangling from the trolley for everyone to gawp at. But it’s a small price to pay for smooth convenience. It´s made by CreativeTools.
Life is too short to put up with bland, flavorless food. Spice up that dish with a splash of Tabasco. Whaddaya mean you ain’t got none? Fine, you can borrow some of ours. It just so happens that we always have the hard stuff handy, thanks to a tiny 3D printed bottle holder nestled among our huge batch of cool custom keychains. You’re welcome.
