Platonic solids
thingiverse
"In Euclidean geometry, a Platonic solid is a regular, convex polyhedron with congruent faces of regular polygons and the same number of faces meeting at each vertex. Five solids meet those criteria, and each is named after its number of faces." -- http://en.wikipedia.org/wiki/Platonic_solid Instructions Just load the object into Makerware and print! I have tested all five objects on my Replicator 2 using the standard make option in MakerWare Version 2.2.2.89. Objects are already oriented with a flat face down, so no rotations etc needed.
