Atom Marble Spinner Customizable

I really liked [growe41's Atom Marble Spinner](https://www.thingiverse.com/thing:2166485) and remade it in OpenSCAD for better marble grip. You can change marble diameter and most other dimensions in customizer. Included STLs are for 15-15.5mm and for >15.5mm marbles. Of course You can use any suitable spherical objects as weights.

Used [these caps](https://www.thingiverse.com/thing:2181061).

Update 2017-06-27: You can now resize the orbits and control the atom positions in Customizer.
