Icosahedron

An icosahedron is a regular polyhedron with 20 identical equilateral triangular faces. It is one of the five Platonic solids. http://en.wikipedia.org/wiki/Icosahedron The fun part was modelling it with the fewest features possible. I got it down to 9 features (8 if you leave it as a multibody part) See if you can do better and post your model back
