600 Cell

thingiverse

This is a shadow the largest of the 6 regular polytopes in 4D. It is made from 600 tetrahedra. This is the dual of the 120 cell. http://www.thingiverse.com/thing:20788 Unlike the other 4D shadows that I have been producing, this model is centered on a vertex instead of a cell. This creates a nicely symmetric model, but it also creates one vertex at infinity. The little stubby edges on the outer part of this model are all supposed to connect to one vertex at infinity. Instructions The inner most edges on this are really thin, so I'm not sure that it would be possible to remove supports without breaking them. I'm in the process of creating another version that has thicker edges.
