This cassis can be used for the well-known chinese 2WD arduino robot that can be bought all over the internet (or take a look at my other Thing!)
If you need some more space on your robot; use this top deck! On top there are mounting holes for an arduino uno and my LCD holder, as well as some universal mounting holes and slots.
The deck can flip up so you can reach the electronics underneath. I have made holes for the on/off switch so you can save valuable space on the robot's building area.
Laser cut this from 3mm material.
