Torso [had] some bad geometry that need(ed) repair and (was) throwing errors. Lots of intersecting geometry. (Update: Artist has since fixed the issue. Feedback was quick and was happy to help.)

The best multipart STL I've ever printed. Didn't have to wrangle with any pieces for a second to get them to connect to each other. Every single piece printed just about flawlessly in a single go using Prusaslicers "Best Surface Quality" autorotate at 85% auto support.
