This is a dodecahedron created by friction welding 12 pentagons together. This is a minor remix to the truncated Icosahedron I previously published. The individual pentagons are printed separately. After printing the pentagons they are welded together using a Dremel rotary tool and a small section of printer filament. The friction welding process works for PLA, ABS, 1.75mm and 3mm filament. More information on the process used for friction welding this thing is available here: http://www.scorchworks.com/Blog/friction-welding-with-a-dremel-rotary-tool/ EDIT: I updated the SCAD file to make it more easily adjustable from a pentagon to other shapes and added comments.
