The head was modeled in Sculptris (first sculpt ever) and was combined in Rhino with a chess piece from http://www.instructables.com/id/3D-scan-your-head-and-use-it-as-an-chess-piece/?ALLSTEPSBecause the final stl is not a completely merged mesh I used in Cura the Expert Settings - Fix Horrible - Combine Everything Type B in order to prevent holes in the model.The hair and head, two different objects in Sculptris, were MeshBoleanUnion'd in Rhino.Printing with a raft is recommended to prevent the model from tipping over.
