I’ve noticed that most of the 3D printed objects here are human body parts. I’d like to add this 3D printed skull by Jesper Knudsen of Denmark. This may not yet be ready full bone replacement, but this can be a huge help for training doctors. http://www.3d2print.net/shop/blog/co...eed-new-skull/ . Also, this rubber filament is good material for experimenting in making different human body parts because of its rubber-like characteristic: http://www.3d2print.net/shop/filament/elastic-filament/
