Four separate .stl files of platonic solids. In order to size them to be typical beads for stringing, ~10 mm, scale them as follows.

• Cube 40%
• Octahedron 50%
• Icosahedron  30%
• Dodecahadron 20%

A .3mf file and a  .gcode file for the Mini/Mini+ are also included.

Note:  The fifth Platonic solid is the Tetrahedron.  It doesn't work very well as a bead, and it's sharper edges would probably be irritating to wear, so I didn't include it.

The files were created using Mathematica.
