Truncated icosahedron - soccerball
This truncated icosahedron wireframe is made of separately printed walls: 20 hexagons and 12 pentagons. The walls fit snuggly together, no glue needed. Feel free to try out various colors for the walls.
The angle between a pentagon and a hexagon is different from the angle between two hexagons. The second version of hexagon has studs in alternating order, so it can be oriented in one way only, keeping the wall angles exact.
