Love this model (LANDRU!) But I refuse to use raft/supports when printing. I added about 25 helper parts in Tinkercad to make 100% printable without supports or raft. Tilted the chin down a touch also so it touches the platform.
I've printed this on Rep2's and Rep2x in PLA using 0% infill, 2 or 3 shells (depending on how see thru you want if backlighting it) and .2 layer height in Makerware. If PLA - having an extra fan trained on the work surface really helps the detail level.
The silver version is a quick paint job. Print in black (or give a complete flat black) paint job. Then give a grazing light silver paintjob. This keeps the eye sockets and deep pockets dark. Then red eye and done.
