Lego and 3D printing are a match made in heaven. How about 3D printed Lego curved bricks, superhero figurines or Lego to Brio converters?

Are you ever just missing that one Lego piece to complete your creation? Sadly, that’s sometimes the case. But anyone with a 3D printer is in luck because 3D printed Lego pieces are easy to fabricate. They might not be the best fitting Lego pieces in the world, but they will do the trick at least until that missing piece under the couch is found.

3D printing has enabled people to design super-sized Lego figures or funny heads of any character they want. This is something that wouldn’t have been so easy without the rise in popularity of 3D printing. These Lego minifigs are fully functional figures with moving limbs complete with accessories.

If you don’t have a 3D printer at hand, you can have the 3D models printed by a professional 3D printing service. To get the best price, please use ALL3DP’s Best Price 3D Printing Service.

Image of 3D Printed Lego: Giant Lego Superhero Collection

This 3D printed Lego collection of 22 figures is really cool. Some of the characters featured are Batman, Darth Vader, Captain America, Dead Pool, Luke Skywalker, Han Solo, Spock and Captain Kirk, Hulk, Captain America, Iron Man, Thor, and many more.

The models are super big like a normal Lego figure could fit inside the hand of one of these, kind of big. Each model, except for two of them, has an accessory. The figures on the photo were all printed on a Robo3D R1 using PLA and a 0.4 mm nozzle at 200 microns.

Would a collection of Lego Minifigs be complete without a Han Solo in carbonite? Although this 3d printed Lego design doesn’t have a detailed face and shirt, these details could be drawn or painted on later.

This time, Han Solo is frozen in PLA or ABS!

3D Printed Lego Blank Minifig

Image of 3D Printed Lego: Blank Minifig

This 3d printed Lego is a generic blank Lego minifig. At four times the size of a normal Lego Minifigure, this 3d printed Lego won’t be compatible with all that Lego lying around, but it sure would make a nice desktop piece.

The hips and head of this model need to be printed using supports.

3D Printed Lego 1:1 Lego Mini Figure

Image of 3D Printed Lego: 1:1 Lego Mini Figure

This is a 1:1 scale 3D printed model of a Lego minifig. The creator says it’s a challenge to print. Other than that, one should be able to interchange parts from the 3D printed model with real Lego pieces. That’s pretty cool. Missing a hand? Just print one out.

3D Printed Lego Zombie Head

Printing Button

This is the perfect model for your Lego zombie apocalypse. The eyes and mouth are separate STL files. This means that any color or material combination is possible for these Lego pieces. The designer suggested printing the eyes with glow-in-the-dark filament and using glue to fix the face parts in place if necessary. This 3D printed Lego head is much larger than real Lego heads, so it will not be compatible with real Lego minifigs.

What a fitting name for the 3D printed Lego Clone Troopers. They are 1:1 scale Lego minifigs that can stand on a base plate. However, the model is one solid piece with no moving parts. One of these Clone Troopers can hold a weapon in his left arm.

3D Printed Lego Lego Thor

Image of 3D Printed Lego: Lego Thor

The next 3d printed Lego is a 3D printable model of Thor. The legs, arms, hands, hips, and arm pieces were taken from this model and the head was taken from this model. The chest and all the other Thor accessories were designed to fit with the other parts. This 3d printed Lego is larger than a real Lego minifig, so it isn’t compatible with real Lego.

Image of 3D Printed Lego: Duplo to Brio Converter Brick

Printing Button

This 3d printed Lego design is based on a different converter brick design, that was too hard for the three-year-old to use according to the creator of this brick. So he designed his own, simpler brick, which is the perfect thing to merge two inspiring classic toy sets.

The designer printed this Lego piece on an Ultimaker without supports.

3D Printed Lego Melted Lego Bricks

Image of 3D Printed Lego: Melted Lego Bricks

Use these melted bricks to add some character to any action packed Lego landscape. The STL files include a double sized version (compatible with Duplo) as well as versions with a thicker base. Also, the designer suggests the bricks be printed with supports and at an angle, making the actual brick-part of the design parallel to the build platform. This will look better than having a brick printed at an angle.

3D Printed Lego Lego Light Switch Cover

Image of 3D Printed Lego: Lego Light Switch Cover

The next 3d printed Lego lets you create a Lego scene surrounding a light switch. Use this light switch cover to stick Lego minifigs, bricks, or other structures to the wall. The model was designed in inches, so it will have to be scaled properly to work for any setups using the metric system.

Image of 3D Printed Lego: Giant Lego Christmas Wreath

Printing Button

This 3d printed Lego is a cool alternative from a real spruce bow Christmas wreath. This 3D model is based on real Lego pieces. Although they aren’t completely identical to the real pieces, this wreath looks really cool. The designer suggests printing the models with supports and at 150% scale in order to get the same size pictured above.

NOTE: The files uploaded to the price comparison service (“ORDER THIS PRINTED” – button) are not scaled up. This means that ordered pieces will not be as large as shown in the picture.

3D Printed Lego Lego Man Toilet Paper Holder

Image of 3D Printed Lego: Lego Man Toilet Paper Holder

This 3D printed Lego man toilet paper holder is not limited to what can be seen in the picture. With some design work, this Lego man could be turned into any character you like. The model is attached to the wall with suction cups, but it should be pretty easy to whip up a different mounting system for walls that won’t work with suction cups.

Make a quadcopter using Lego. Basically, the designer has provided the models for the pieces holding the motors as well as the piece at the center holding everything together. However, the designer urges not to use the STL files uploaded to the Thingiverse site, but rather to use the OpenSCAD project to alter the parameters and generate custom STL files for your own Lego quadcopter design.
