easter egg painter helper

This was my first design done while learning blender and it doesn't really fit in terms of quality of the source code (I lost some blender file on the way).

I am publishing this as I find the design simple and effective and we are nearing Easter. It started as and eggbot clone but my kids preferred to let the egg turn and draw themself. The metal parts make is easy to create larget objects without needing many hours of printing. Given design is so simple I hope to inspire somebody to convert
