About this 3D model
A bust of a grizzled old alien I drew up in Sculptris. He's pretty high poly (roughly 100k triangles), so he'll be a pretty good demonstration of your printer's quality. And if your printer messes up near the end (like in my first attempt), he makes a pretty nice container for your tools! I've attached the Sculptris file in case you want to make some changes of your own. The base isn't flattened in this version.
