Pyrolytic graphite demo box

Very simple parametric demo box for showing magnetic levitation of a pyrolytic graphite sheet over permanent magnets.

The top border prevents the sheet from falling off the magnets.
The lid makes possible to close it as a box (but there is no bottom, magnets hold in place by friction).

Material:
* pyrolytic graphite sheet from Aliexpress
* 20 30x10x4 mm neodymium magnets

Real size of the magnets was more about 28.95x9.51x3.75 so if you want to reproduce this toy, measure the real volume of your magnets and adjust the scad file accordingly.
