3D printing Lego bricks and pieces is a great way to expand your collection and make some unique, and even practical, additions to traditional sets.
It’s no wonder people all over the world are learning how to 3D print Legos for themselves, especially since Lego pieces are already made using ABS, one of the most common 3D printer filaments in the world.
Here, we’re going to look at some of the coolest and most interesting 3D printed Lego pieces and figures still available as STL files you can download and print today.

The included customizer lets you print standard Lego bricks with text such as names, slogans, or emojis, enhancing your project with text-based art.
The files found also include a default style for a simple, textless brick, so adding letters is an optional feature.
3D printed Lego bricks with text make for excellent additions to a build, and there’s even a separate key fob design for a cool keychain addition or gift.

3D Printed Lego Ferry
- Download: MyMiniFactory
- Designer: Tomaz Tomsic

If there’s one downside to traditional Lego bricks, it’s that they don’t float. Many builders have designed and created their own boat for their figures only to find it sinking to the bottom of the bath in no time.
In response, this designer made a 3D printed a Lego ferry with included files for floaters to keep this lovely-looking boat above the water where it belongs.

This Lego-compatible Batwing brings one of the caped crusader’s many vehicles to life for your little vigilante.
3D Printed Lego Weapons
Lego figure hands can hold various weapons, from bows to lightsabers. Since few of these items are sold separately, many people 3D print custom Lego accessories to add some attacking flair to their minifigures.
Bow and Arrow

This simple 3D printed Lego bow and arrow is a cool little model for anyone building a warrior. The original STL files were designed on a 1:1 scale and then blown up to fit the large Lego models pictured.

The blue blur is as recognizable today as he was in 1991, and this design for a Lego figure compatible Sonic the Hedgehog head is hard to beat.

Christmas Lego Pieces

Practical 3D Printed Lego Models
Not all 3D printed Lego models are for use with traditional Lego sets and minifigs. Many people have taken to designing and printing practical Lego-inspired creations for use around the house.
Usable Lego Cup

How to 3D Print Legos
Finding the right STL files for 3D printing Lego pieces can be challenging if you’re not designing your own.
Cults3D and MyMiniFactory are the go-to platforms for this purpose. They offer the largest range of designs, are almost always free, and feature an easy-to-use search function.
Once you’ve downloaded an STL file, you can resize it to make Lego-compatible parts that fit your specific project needs.
Perfect Filament
Lego pieces are made from ABS, meaning they’re perfect for recreating with ABS filament. But be warned, the official company has recently been cracking down on unofficial Lego pieces and figures.
If you don’t have access to ABS, other sturdy materials like PLA+ work just as well.
Measure and Remeasure
All Lego parts need to be exactly the right size. While many of the STL files we’ll talk about here are designed to be on a 1:1 scale with standard Lego collections, it’s still a good idea to double-check the sizes in your preferred editing software to avoid disappointment.
There’s nothing worse than being excited about your new Lego pieces only to find out that they’re a millimeter or two off from fitting the way you want them to. Aside from stepping on them, of course.
Post-Processing
When making Lego pieces, you’ll need to make sure each brick is the right size and shape so they can all fit together. But to make sure they all fit together nicely, you’ll need to take great care in post-processing to get the smooth surface you’ll need for the Lego pieces to all attach the way they’re supposed to.
Each filament will need different kinds of post-processing to get the ideal results. So be sure to look at the recommended steps for your type and brand before you get to work.
