Hollow clock with flying hands

Remixed the fantastic idea of the levitating hands clock with proper gears and a stand to hide the electronics. For partlist and software please visit [original model page](https://www.thingiverse.com/thing:4761858).

Tips:
- fix Arduino and wires with hot glue after soldering
- maybe hole pattern doesn't fit to any stepper driver, but one screw should work ;)
- drill Ø5 and Ø6mm inner holes of the gears to assemble them with less force (danger of part breaking)
- fit gears with a small gap to keep them moving easily
