About this 3D model

I've been experimenting with lost PLA. The first part we tried was a half scale version of the make robot. The guy I'm working on it with suggested we add on a ring for a necklace or jewlery so I did.The ring was added in meshmixer. It does have a self intersection at the hands. Skeinforge does fine with this, but can't speak for others. The first attempts to print this in PLA just left a mushy blob for the keychain. So I ran one in ABS while the PLA cooling fan upgrade was printing. More details and pics to come on the casting side Updated: Added second model with loop sideways.
