Cool things to 3D Print in 2024

Picture Frames

So you have all these lovely photos on your phone but haven’t found a nice way of presenting them? Just have them 2D printed and fire up your 3D printer to gain an extra dimension. The frames are designed for 52 x 86 mm photographs, but you can scale the frames to your liking.

 

Clothespin

This minimalistic, medium-sized clothespin is easy to 3D print in one go without the need for support structures. We recommend printing it with PETG filament, as it’s sturdy, weather-resistant, and flexible.

 

Fruit Bowl

Even though most filaments are food-safe, FDM prints aren’t ideal for long-term food storage, as bacteria can grow in the layer gaps. All is fine once you seal the surface with waterproofing spray, a clear coat, or even water-resistant paint.

 

Soap Holder

The self-draining holder stands on four tiny feet, which should be printed in TPU for a better grip on the surface. PETG will do fine for the rest.

 

Stackable Crates

Here’s a modular set of 56 crates. It can hold batteries of all kinds, from the smallest AAAA to 9-volt blocks and CR-type batteries. There are also dedicated prints for storing SD and microSD cards, memory cards, plus USB and USB-C flash drives.

 

Soft Tape Measure Spool

A cloth measuring tape is something most people have in a drawer somewhere. Normally the tape starts to unwind and is all over the place, but with this simple, print-in-place design, you tame it. A small winder lets you pull it back once you’ve measured.

 

Brick Stackable Desk Boxes

Existing in a space somewhere between playfulness and cleanliness, these stackable desk boxes can be attached and detached easily. They are five times the size of a certain iconic brick brand, and bring a bit of childhood nostalgia into your office.

 

Hanging Lamp

The highly diffused light shines evenly through a thin layer in the middle. We don’t need to remind you that you only should use LED bulbs due to heat reasons.

 

Birdfeeder

There’s no shortage of cool birdfeeders designed by the 3D printing community, but we found this model to look particularly stunning. Although the design might look difficult to print, it can be printed standing up without support structures. All you need is a large brim for better adhesion of the print.

 

Hand Crank Generator

Magnets and kinetic energy is a versatile and, great to generate electricity. All you need for is some basic parts (bearings, copper wire, diodes, capacitors, and high-grade magnets), and a free weekend.

 

Low Poly Tray

If you’re looking for a simple, stylish tray to hold your stuff and look good doing it, this is the free model for you.

 

Desktop Trash Can

For some of us, keeping your desktop tidy can become quite a feat. So, with this three-part print (can, top, and lid), you will have a place for all those chocolate bar wrappers, and pencil sharpener waste.

 

Zen Garden

Most parts can be 3D printed; just add some sand, small rocks, and a plant.

 

Cable Repair

Our phone’s charging cables see daily use, and most of us aren’t too particular about unplugging them carefully. So, these cables have a tendency to break. If your Samsung USB-C or iPhone Lightning cables show signs of wear and tear, print this and attach it to the cable to keep it from breaking.

 

Miniature Nerf Blaster

After having built the world’s largest Nerf gun, YouTuber and engineer Marc Rober wanted to go for the opposite: The smallest working Nerf gun in the world. He and a team of scientists managed to shrink a working Nerf blaster to the size of a hair and even go beyond that.

 

Headphone Hanger

The headphone holder fits any tabletop up to 25 mm thick and can handle a headband width of 45 mm wide. It’s also great for hanging a backpack or handbag out of the way.

 

Toilet Paper Roll Holder

This Shawn-the-Sheep-themed model holds one roll, is easy to print and assemble and looks as fluffy as a sheep itself.

 

Simple Card Box

This print is done in no time; you won’t need support structures and it will keep your precious card decks intact and complete.

 

Bottle Cap Boy

If you’re looking for a way to find a use for waste plastic bottle caps, this is a fun project.

 

Flat Pocket Whistle

This whistle is small, looks great, fits snugly on a keyring, and emits a clear, high dual-tone sound. Despite its size and height, it’s actually quite loud!

 

Mini Hanging Storage Container

This two-part mini container safely stores small items. For example, you can use it for medication or to store geocaching items in it. You can also attach it to a keyring, wear it with a leather band around your neck, or attach it to your backpack.

 

Shoe Organizer

Since we all know how much space shoes can take up, master the mess with this 3D printed rack which helps you to store your shoes in a practical and space-saving way.

 

Minichess

Printing the board and pieces should be straightforward, and you can make the set satisfyingly with small magnets to hold the storage tray in place.

 

Gravity Broom-Holder

It uses a rolling gear and the broom’s weight to clamp the stick securely. To remove it, slightly lift the handle towards and outward the direction of the gear.

 

3-Digits Combination Safe Box

This safe uses a 3-digit combination to prevent anyone from snatching your valuables. Of course, it’s not as secure as its steel counterpart (you can melt or crush plastic, right?), but it’s a fun project anyway.

 

Tally Counter

It counts up to 99, and you can also subtract numbers.

 

Hexx Case Tool Roll

These individual compartments can be rolled into a compact hexagonal toolbox, and still, everything stays in its place.

 

Oreo Box

Now you can print this handy Oreo Cookie Box! The 3D printable design has been around for a while, but this particular model has been completely revamped.

 

Battery Dispenser

It holds 20 AA and 35 AAA batteries.

 

Squeeze Fan

Is it getting hot outside? Are you in desperate need of cooling? Well, this 3D printed fan, once assembled, can actually be used to cool you down. It is powered by a squeezing mechanism that doesn’t require additional batteries.

 

LED Hexagonal Panels

Is it a lamp? Is it art? Is it both? That’s for you to decide.

 

Slim Credit Card Wallet

Press the button on the back of this wallet and up to five cards will slide out.

 

Quick Grab/Release Phone Stand

This phone stand not only allows multiple viewing angles, but also offers a quick grab/release mechanism, locking the phone tightly in the stand and releasing it when you pick it up.

 

Groovi Monster Sound Amplifier

This is a passive amplifier for your smartphone, which adds a little extra “oomph” to those tinny speakers when blasting out your tunes.

 

Self-Watering Planter

Houseplants dying from neglect? NEVER AGAIN. Print off this automatic plant waterer, and your conscience will remain clean.

 

Digital Sundial

Your eyes do not deceive you. This insanely cool thing to 3D print is a digital sundial. And it really does work. The shape of the sundial has been engineered to only let through the right rays at the right time and angle, so it can display the actual time at 20 minute intervals.
