Busy Cube #1 - Simple Switch

This specific project serves two purposes. First, I wanted something small and simple that will keep him entertained during plane and car rides. Second, I used it as prototype before making something more sophisticated (with a micro-controller, rechargeable battery, and all the other goodies).
The design itself is simple - there’s the cube structure itself (made of 6 pieces of plywood), and the on/off switch module. The later includes the switch, and two battery holders that are glued to it. This whole unit slides into the cube, and then secured with four small M2 screws.
I’m participating in some contests, so if you liked this instructable, please don’t forget to vote!
(I apologize for the quality of the photos in this Instructable. I was in a hurry to get this done, and all I had was my phone and very bad ceiling lights in my office)”
