Happy holidays! We wanted to share these STLs in time for those of you who celebrate Christmas.

A truncated icosahedron consists of 12 pentagonal faces and 20 hexagonal faces (not unlike a soccer ball): https://en.wikipedia.org/wiki/Truncated_icosahedron
This model was designed to minimize infill. If you're using a slicer that can assign different settings by model (e.g. with processes), you could use these settings to minimize infill:
- 0 top layers on the bottom segment
- 0 top and bottom layers on the middle segment
- 0 bottom layers on the top segment
