LEGO is a trademark owned by the LEGO company and has nothing to do with me or these files. I make this note now because they are taking down my files in a weak attempt to protect their fading legacy. Listen to me Lego, you can sck my Fcking Di*K!

This is part of a set of customizable Lego compatible robotics components. This post is for Lego compatible mounts for an Arduino nano with an expansion board (an UNO would also fit as it is the same profile).

Files Included:
A brick that covers the nano so you can make use of the space on top.
A case for a 9V battery and mount for a breadboard that can snap to the top of the cover.
A version of the nano-cover with a space for holding a dual motor driver.
A 2x2 brick for holding a buzzer. (useful for trouble shooting robots)
*A customizer for standard Lego bricks

All parts shown printed in ABS, but I've also successfully printed with semi flexible TPU. Printing Legos is tricky, see the print settings section for tips.
