This dodecahedron has tapered faces and is entirely shelled to create intricate surfaces. The top has an opening to avoid excessive overhangs. FDM 3D printer friendly, this requires no support material to print properly. This comes in two sizes, small and jumbo. Great for a timelapse, demo or calibration.

This was inspired by XYZAidan's Dodecahedron 123D Design tutorial: https://www.youtube.com/watch?v=EicqAfRp7rg
