Rubik's Magnet

Rubik's cube magnet version.

There are some different versions:

Small version: On photo seen is a cube with 12mm cubie sidelength. I have started the 20mm cubie version (standard size). Because it takes a very lot of filament and my magnets are to small, I have cancelled this size.
Small Version takes 5x2 neodymium magnets. The holes in cubies for magnets have different depth. Center needs most strength, it is not so deep there. I have inserted the magnets and then I have melted the plastic around with solder iron. Check direction of the magnets before inserting.

Big version: You'll need 5x3 magnets.

Screw version: refer to openscad screenshot:
Buy a standard cube core. screw the mid pieces around (mid pieces with screw holes are g_.stl). Add the other pieces around for a 3x3x3 cube.

If you like to make 5x5x5, use inner mid piece e_.stl and outer mid piece f_.stl. Same if you li
