About this 3D model

A small, battery-powered gyroscope. Update (6/29/10): Here's a video of one in action. Note that I used 4 button cells instead of 2. http://www.youtube.com/watch?v=Ov5WVhhIdWo Update (6/30/10): Added a DXF file for lasercutting. If you use 5mm stock, the result should be about the same. You'll need to drill out the pivot holes, though.
