3D printing is such a fun way to produce creative work—and it has totally taken off. Now, creators are using this amazing new technology to create all kinds of wild and wonderful 3D printer projects that were previously all but impossible to make at home.

These 3D printer projects are a great addition to your online design portfolio. This is such a hot space that showing your mastery of this chic craft could win you some big new clients.

Want to get in on this cool 3D prints trend? We’ve compiled a list of 63 inspiring 3D printing ideas to fuel your next 3D printer design. So, what can you make with a 3D printer? Well, there’s something for everyone!

3DBenchy

The 3DBenchy appears to be nothing more than an adorable plastic boat, but it’s more than that. This little guy was designed specifically to test the limits of your machine and calibrate it to operate optimally. It’s one of the simplest—and most useful—3D printer projects you can start with.

Survival Whistle

Next in our list of cool things to 3D print is a simple project that can be completed in approximately one hour and will produce a whistle. It can produce an eye-popping 118db sound, perfect for camping or sporting events.

Sunglass Visor Clip

A handy and practical creation—and one of the simplest 3d printer designs on the list—this quick-to-create project allows you to affix your sunglasses to the visor of your car.

Earbud Case

If there’s one thing we can all agree on, its that earbud cords are a pain in the butt to keep organised. They constantly get tangled and eventually produce the dreaded earphone-crackle, rendering your treasured music-makers useless. This is a great example of what you can make with a 3D Printer that can improve your everyday life.

Carabiner

This carabiner is surprisingly durable, with a strong frame and a flexible hinge. It can withstand up to 30kg of weight, which is pretty substantial for rendered plastic! Don’t, however, be tempted to use this to support your own weight, as they are not designed to support that much strain.

Flexi Rex

A simple toy originally created for Settlers of Catan, this project is durable and (in our opinion) cute. This is one of those 3D printer projects you could use in a few ways: gaming, office desk decoration, children’s toy, you name it! Plus, T-Rexes are (always!) cool.

Get your headphones off your desk and onto a specially crafted hanger of your own design. Great for home and the office, these are the kinds of simple and effective 3D printer ideas that can make a big impact with very little effort.

Bowl

With a 3D printer you’ll be able to replace your dinnerware with new and original 3D printer designs in no time at all. Take this blueberry-themed bowl, for example. Why stop there? There are numerous other designs for plates and bowls out there to make eating at home a unique experience.

Planters

Why use traditional planters to hold your plants? There are cool 3D prints out there that don’t allow you to skip the traditional clay pots. These modular little guys are modern and fresh and guaranteed to make your mini-garden more attractive.

Platform Jack

While it won’t be holding up a car in a garage any time soon, this platform jack can still withstand a fairly reasonable amount of weight, allowing you access pesky undersides. It’s great for painting models and other hobbyist tasks.

Sometimes the office gets boring. Pass the time by constructing these fun things to 3d print: little catapults! Work on your (probably) lacking marksperson skills with these adorable wee “weapons” that can fire small projectiles up to two meters away (perfect for mastering your paper-in-wastebasket game).

Cutlery

If you dig camping, or just want a convenient set of small cutlery for use at the office or in the cafeteria, you can’t go wrong with this 3D printer design. They’re functional, portable, and take only a short time to create!

Keychain Smartphone Stand

Nearly everyone these days has a smartphone, and we’ve likely all had moments where we wanted to prop up our phones for viewing video or photos and had to resort to piled books or whatever else is on hand. And it rarely works out as well as we hope! That makes this tiny project one of the coolest 3D printed objects on the list. Plus, they look like cats. Cats are good.

Business Card

A truly inspiring 3D printing idea, these pop-out business cards allow you to speak to clients in a way they won’t have experienced many times (if ever) before! Rather than a drab piece of cardboard, hand them a toy they can assemble that speaks much louder than a traditional printed card.

Fidget Spinner

Can’t sit still? Searching for a 3D printer project to help you focus? Look no further. Fidget spinners are an excellent way to occupy your mind, and this 3D printed object will definitely do the trick.

Tin Can Dumbell

We’re all trying to squeeze in any little bit of exercise we can into our busy days. This is a cool 3D print for folks looking for office or hotel fitness hacks.
