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 shows your mastery of this chic craft could win you some big new clients. You can showcase a collection of cool things to 3D print and some of your best 3D printings too.

Want to get in on this cool 3D prints trend? We’ve compiled a list of 67 inspiring 3D printing ideas to fuel your next 3D printer design. So, what can you make with a 3D printer? Well, there’s something cool for everyone!

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.

If there’s one thing we can all agree on, it’s that earbud cords are a pain in the butt to keep organized. 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.

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.

Organize your desk, and add a little flair at the same time! With these simple 3D printer designs, you’ll have all you need to generate truly unique desktop organizers that not only keep your stuff where it needs to be but look cool as well. You can 3D print a pencil holder that is unique to your own personality and have others mistaking your pencil holders again.

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.

One of the cool things to 3D print is an abstract planter for your succulents and cacti. 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.

Measuring Cube

Get rid of those 72 measuring spoons from your utensil drawer and replace them all with a single implement! One of the most immediately useful and cool 3D prints in this list, it’ll make for an interesting tool that others will want when they see it.

Cable Holder

Stop the tyranny of cords taking over your desk and entertainment unit and 3D print some space-saving cable management devices. You’ll cut back on desk clutter and all that cord-related aggravation. These are the blessed 3D printed objects that make life a little less annoying!

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.

A perennial childhood favorite, kids love them just as much today. Of course, adults can enjoy these toys, too. They could be just the ticket to break through some creative block!

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.

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.

This is probably one of the most fun and cool things to 3D print, these gimmicky little toys are quite literally affixed to food items found in your house. A lemon helicopter? A banana-car? Why not! Easy to print and awesome for providing hours of enjoyment to restless rainy-day kiddos.

Definitely among the most interesting and cool things to 3D print in this list (and showcasing a bit more complexity than other entries), the dragonfly is a tiny little flying machine you can whip up in a short time. It’s perfect for providing a little entertainment for your kids on a rainy day.

Why settle for boring cutlery in your drawer? With minimal effort, you can produce some decorative handles for your eating utensils and wow visitors to your humble abode. When they inevitably ask “so, what can you print with a 3D printer?”, you can tell them they’re eating with it!

Drop your phone into these useful little devices to amplify the sound from its speakers. They offer surprisingly high-quality sound—and now you don’t need to lug portable speakers around on picnics or at the beach.

If you’re looking for some more simple and cool 3D printing ideas, consider 3D printing a set of drink coasters. Thanks to simple 3D printer designs like this, we won’t need to spend our hard-earned cash on flimsy little discs anymore. Make your own coasters with whatever designs you want, and say goodbye to tacky freebies and over-priced novelty ones. This idea makes for one of the cool things to 3D print as gifts!

If you’re an audiophile, you’ll truly appreciate this entry as one of the best things to 3d print. By converting audio files, you can create your own records that will play on turntables. Why limit it to music? Record your own special messages to loved ones and send out the love!

Simple 3D printer designs like this are great to have on hand. Hinges are always useful, and come in handy all over the house. These particular designs are super-simple, even by 3D printing standards, requiring just a single step!

With a sliding clasp, these unique chip clip designs work quite well and are fantastically simple things to 3D print.

A larger-scale project than other 3D printing ideas, the Drawing Machine is quite unique: attach a pen and create works of art from files on your computer. This 3D printer project can help you produce invitations, cards or any other manner of drawings.

Some nostalgic old-timey engineering comes into play with these uber-neat 3D printing ideas. Relive the past and have your desk decorated with a sign that uses something other than LED or LCD displays!

When it comes to 3D printing metal, there are people who may choose to use a laser cutter instead. The reason is that 3D printed projects using metal can be costly and time-consuming. However, the two are quite different. 3D printing is an additive process, while laser cutting is a subtractive process. Depending on your needs, those that are looking to create multiple pieces at a quicker pace may choose the laser cutter as it can conveniently cut multiple materials and larger size.

With digital trends of raw and rustic design, you might be considering 3D printing cool things at home with metal. However, printing metal is extremely costly due to its process and the machinery required. If you’re looking for cool things to 3D print at home with a metal-looking finish, we recommend using materials on the market that can create metal-like 3D printed objects instead. These materials give the illusion that your 3D printed pencil holder or camera mount is made out of metal but without the actual cost.

Thanks to 3D printing, it has also made highly-customizable prosthesis possible. One of the coolest things about 3D printed prosthesis is that they can create custom fits for the patient and also a much lower cost. Instead of creating static designs that are “one size fits all”, 3D print gives companies the opportunity to create products that are affordable and personalized. What would have cost lots of money to create is now more accessible thanks to 3D printed prostheses.

Beyond science, 3D printed homes and shelters have also become one of the cool things to 3D print across the world. To address the housing issue around the world, companies have been using this technology to print emergency shelters and 3D printed homes. With this technology, companies and cities can build a community in a much shorter amount of time and for a cost cheaper than traditional home building methods. Each home inside the community can then be purchased at a more affordable cost.

If you love architecture and buildings, companies have created kits that allow people to replicate architectural structures and other cool things with a 3D pen. For boardgame lovers, you 3D print your own figurines by drawing it with your 3D pen. You can also turn your favorite cartoon show characters or movie heroes into 3D. While a 3D pen allows you to draw 2D things to 3D, their limitation tends to be the size of the project you can make. If you’re looking to 3D print a life-size chair, it may be easier to use a printer because 3D pens may not be able to create something as durable.

Tangram: A super easy and fun game to play with your kids or friends. If you’re going on a road trip or simply trying to pass time, this 3D printed tangram makes for portable entertainment.
Klöts (Quick shoe ties): Some cool things to 3D print for your kids are these quick shoe ties. With this project, you’ll spend less time worrying about their shoelaces being undone and risking a fall.

Door Stop: Some things to 3D print for practical uses are these door stops. Whether you’re using it at home or for your office, printing them is super easy and fast.
