Scapula_cut1.stl and Scapula_cut2.stl prints without support and raft on my Replicator 1 (white ABS). There are decent overhangs, but it came out good I think.
I glued with acetone.
Skeined with SF50 and printed with Sailfish firmware at 120mm/s, 0.2mm layers, 2 extra shells.
I include original .stl as converted from BodyParts3D .obj if anyone wants to come up with a better way of cutting for example.
