We’ve reported before on the unique 3D printing achievements of Matt Denton, who runs the Mantis Hacks Youtube channel. Denton has used 3D printing technology and LEGO construction bricks to put together some impressive builds, with videos recording his work. He also has a long career in the TV and Film industries, contributing visual effects of various kinds to such high-profile franchises as Harry Potter and Star Wars, through the Micromagic Systems company that he founded in 1999. Denton has recently posted another video on his channel, demonstrating his huge 3D printed LEGO Bulldozer.
While this might sound like a real one-of-a-kind 3D printing project, Denton has actually worked on some similar things in the past. He posted a video of a giant 3D printed LEGO forklift not so long ago, as well as a giant remote-controlled LEGO Go-Kart. This latest project was carried out in collaboration with Denton’s nephew.
The bulldozer was based on the LEGO Technics kit for a bulldozer, which is made up of a total of 372 parts. Denton decided to take this design and make his own huge 3D printed version, hopefully running the moving parts from an electric motor.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7:30pm ET! To join, head over to YouTube and check out the show’s live chat and our Discord!
