This is a Remix of Just nude... by Medelis.
Basically I've just cleaned up the original file, which clearly wasn't created with 3D printing in mind, as it contains both 2D and internal geometry.
The hair which was made of overlapping 2D layers now has depth and should form part of a single solid body when sliced. Some of the other bits of superfluous or unprintable geometry I've simply removed.
UPDATE:
Ive uploaded an stl of the head as a test print as someone was still having problems getting the hair to print properly for reasons i don't understand.
