About this 3D model

12 copies of this shape form a sphere based on the structure of a dodecahedron. The addition of magnets on the sides means that you can assemble this object very quickly and have a nice stable shape. Furthermore you can assemble the object by putting the 12 pieces in a box and shaking the box. This was inspired by a video on [self-assembling viruses](http://youtu.be/X-8MP7g8XOE).
