Like us, you’re tremendously excited by the possibilities of 3D printing. Unfortunately, the landscape is cluttered with trinkets, doodads, and ornaments. We’re in danger of drowning in 3D printed objects that nobody wants or needs.
Fight the tide of mediocrity! Let’s make stuff that’s useful! Here’s a list of cool things to 3D print, right now, today. Prove to your nearest and dearest that there’s an everyday and practical application of this wonderful technology.
Updated monthly under the guise of our very own printocracy, each month we remove the five least clicked models and replace them with five new printables. As the year trudges on there will always be something new, while the uninteresting items drift away. Simple!
Bowl Set - Table7 Collection
Let’s start the New Year nice and easy. No fancy projects. No complicated builds necessitating the purchase of extras; just simple, stylish bowls to hold all the nuts you’ve been cracking.

Most Common Metric Nut and Bolts - M2 Through M20
See, still nice and simple – no fancy-schmancy prints that are all style and no substance. Here’s a cluster of common nuts and bolts, from teeny tiny M2s (that we’d probably not bother trying to print on a desktop machine) all the way up to the chunky M20. Handy stand-ins for your next project if you’re in a pinch and need to hold something together.

Ratchet Clamp Print-in-Place
A strip of interlocking teeth make this clamp self-locking, and being print-in-place too, it’s practically foolproof. Challenge: How many of these can you attach to someone before they notice? Let us know in the comments.

PolyRocks // Climbing Holds
Stay-at-home curmudgeons that we are, the New Year brings a sense of optimism for the new that even we can’t deny. Time to try new things, go outside and take up a hobby or sport, get active and love life. Or, have the best of both worlds by populating your living space with these nifty rock climbing holds. Stay at home and be active.

Nutcracker
‘Tis the season to inexplicably eat more nuts than the rest of the year. At least they’re hard-earned nuts though, physically wrenched from their shell in a festive show of strength that, again, is not typical of the rest of the year. Just buy shelled nuts people. Or don’t. If not, this nutcracker cracks nuts like nobody’s business.

Goodman AA
One of the more elaborate and involved builds we’ve featured on this list, the Goodman AA kicks VSCO to the curb with real physical hardware, most of it printed, and the satisfaction of a project well made. Adding a transparency filter of you choosing alongside variable depth of field for your smartphone snapping, the results are mind-bendingly good. Signing up to the Goodman website is necessary to access the files, but that’s no bad thing since there’s a bunch of other open-source camera and craft projects for idle hands to tackle.

Pandoro Tea Light Candle Holder
An easy print to ring in some little festive cheer, this Pandoro-inspired tealight holder has a lithophane-like effect when lit from within.

Universal Zip Toggle
We’ve all been there. A zip pull breaks, curse words are said, and a hastily repurposed key ring becomes the only thing between you and a permanently open bag. But no more! This effortless two-part print has your back and then some.

Entitled Goose from Untitled Goose Game
Print out your own antagonistic Anatidae from hit goose simulator Untitled Goose Game. Available in single- and multi-extrusion versions for your post-processing preference, this print can be enhanced with a magnet to hold a variety of metal objects.

Bottle Opener and Cap Gun
When tackling a problem, it’s often said not to try to reinvent the wheel. The simplest solution is often the best. But let’s be honest, if you could take the wheel and then launch it across the room for fun, that’d be pretty cool. For this bottle opener gadget, as with the Jar Dispenser above, all you need is a few simple printed pieces and an elastic band (plus a few screws) for the fun to commence.

Mechanical Keyboard - SiCK-68
More of a project than a simple printable, given the wiring and firmware fiddling involved, but this mechanical keyboard is, as its name suggests, too sick to pass up. The colors, the compactness, mechanical switches, and satisfyingly simple but beautiful printed parts all add up to a cool looking peripheral you’d feel proud to use. A little indulgence for those with the wherewithal to give it a go (we plan to!)

Money Clip
Flash your cash on the down-low with this quick and easy print. Print on its side and feel that knobbly texture under your thumb as you fling a few fifties toward the barkeep… What drinking problem?

Headset Holder
We’ll always have a soft spot for the Duck Headphone Hanger, but this can carrying solution is eminently cooler. We hope your high school French is up to scratch because the instructions are encapsulated in a slick YouTube video by French channel Heliox. Auto-translated closed captions to the rescue!

Balcony Box
We’re not sure we’d leave it on our balcony, but one thing we can be sure of is that the Balcony Box is the most satisfying fiddly container. This printable cadre of parts slot together with no additional tooling, vitamins or adhesive, resulting in a sleek and compact container that spits apart at your beckoning.

Shoe Support
Keeping your kicks high and dry from the catastrophe of closet clutter, the Shoe Support is a simple solution to a simple problem. Wedge your shoe into the opening and let gravity do the rest.
Some comments on the model raise the concern about the support digging into and potentially marking shoes — we’d recommend softening the edge with a fabric or cushioning of some sort.

Reittec Polisher
This Reittec Polisher uses household items, easily sourceable electronics and a whole heap of silicon carbide sand to take the effort out of post-print processing. Once printed and assembled, all you need to do is throw your print in need of processing into the sand for a long tumble. Several subsequent tumbles in increasingly finer grades of sand later, and you have super smooth parts with not a lick of sandpaper or cans of elbow grease in sight.
The model’s maker outlines the basic assembly steps on the Thingiverse page, but expect to have to fill in a couple of the blanks. Overall though it looks simple enough. For a better look at the build check reittec’s Instagram page.

Smart Wallet
Smart in the sense that a suit can be smart, the Smart Wallet packs a nifty set of compartments for your daily carry essentials into a sleek, pocketable design. With room for a key, parking ticket, credit cards, and a few bills, it subtly fans out to eject the cards housed within. Just don’t expect it to play Netflix, or turn your lights on.

Hose Connector Cusomizer
Ideal for connecting small tubes to slightly smaller tubes, or even – get this – bigger tubes, this connector design will save you a wasteful trip to the DIY store.

Parametric "Print in Place" Containers
We’re a lazy bunch here, which makes anything that’s print-in-place – giving complex function with the minimum of effort, no tinkering required – pretty special to us. And these single-print self-fastening boxes are pretty special. We could hardly contain our excitement for these containers if you will.
There’s even a Fusion360 file on the link, letting you scale the model as desired without ruining the hinge’s printability (scaling directly in Cura will mess with the clearance, loosening or tightening the hinge beyond usability.)

Sheep Toilet Roll Holder
Do you use a lot of toilet paper? Or do you find yourself constantly running out and yelling for someone to come save you? There’s no perfect solution, but this Sheep Toilet Roll Holder comes close by holding a whopping seven rolls at a time. Sure, you could have an ordinary toilet roll holder, but that would be baaaaad in comparison.

Piggy PiggyBank
What is it? A funky looking hog designed to scoop up your spare change. Supports are needed for the rim of the cap on the bank’s underside, but besides that, all is as appears, with no trickery or advanced settings for printing. A simple piggy for a simple job.

Geneva Roller Ruler
You ask a reasonable question, with no measurable timeframe the answer. They facetiously reply “How long is a piece of string?”. You fist-pump triumphantly, “I do, you metaphorical trickster.” Producing the Geneva Roller Ruler from your pocket, you yell “Behold.” Awe ensues; respect earned.
Be in no doubt about the length of turns of phrase, or indeed any turn, curve and non-linear stretches of things ever again, thanks to this 3D printable measuring device. Needing only a couple of Philips head screws and few printed parts, this Geneva Roller Ruler can help you measure along a path in 5mm increments.
