Had some trouble with the hair and self-intersections of the original models, so I gave the hair of the »sexy nude girl with printable hair« a try. I deleted the self-intersections also. Still need to print it, but the print preview already looks perfect. Two parts (hair and body). I uploaded a two piece version (hair and body as seperate meshes) and a one piece version for better 3d printing. I also uploaded my manual support file but feel free to use different support.
