Truncated Icosahedron Puzzle
Quite challenging to assemble this puzzle. I bet you can't do it.
This design is my improvement from this

I improved the rubber band locking gaps and made the external faces at 40 degrees to better mate to adjacent parts.
UPDATE: Uploaded a bigger version (150% scale). The pictures show the small version.
