This is really cool. I'm a little confused by the supports within the sockets (except they're sideways, so not really supports - but they look so thin they'll probably vanish from the slicer.

I noticed in the 3D model that the balls looked bigger than the sockets (slightly), but figured maybe they'd squish a little given the slot in the middle, however I can't get two printed parts together without breaking them. Any suggestions?
