Dodecahedron

A dodecahedron is any polyhedron with twelve flat faces, but usually a regular dodecahedron is meant: a Platonic solid. It is composed of 12 regular pentagonal faces, with three meeting at each vertex. http://en.wikipedia.org/wiki/Dodecahedron I tried to make this model as a single solid body using the minimum number of features. It has 10 features. See if you can do it in less and post back. Have fun
