UPDATE: fixed Y2 issue in thingiverse.com/thing:13802 to enable both parts to be printed with Mr. Colbert.
you may have noticed mrule's lovely Snap-together polyhedron vertices thingiverse.com/thing:4893 and thought, "You know would make this better? The likeness of great American entertainer and statesman Stephen Colbert. thingiverse.com/thing:9104
see thingiverse.com/thing:4893. Additionally, one might notice thatthe undercut on Mr. Colbert's chin is not achievable with most FDM processes. While some might experience print defects, I see only a magnificent Col-beard.
I've included the OpenScad source. make sure to include Y1.stl and Y2,stl from http://www.thingiverse.com/thing:13802 (fixed from thingiverse.com/thing:4893) and
"Colbert LowRes Brow.stl" from thingiverse.com/thing:9104.
