3D Printed BMO with LED Matrix Face

Make your own BMO with 3D Printing and DIY electronics. This adorable robot features a mini 8×8 LED matrix and GEMMA, adafruit’s tiny arduino-compatible micro-controller.

3D Print the parts, solder the components and assembly this cute video game robot to have an awesome adventure time!


Grab the files on thingiverse and 3d print the parts in your favorite color.


The Mini 8×8 LED matrix powers 64 LEDs to display bright and super cute animations. Here’s what the complete circuit looks like. The push button should also have enough slack for it to move around in the enclosure. Gemma acts as BMO’s brains, while the LED matrix+backpack is his face. We can assume the battery is his heart 😉


You can print BMO’s buttons in different colored ABS or paint each piece.
