I'm not sure how I missed this thread.
I was testing sealing a Curvy Copter Skewb but that test piece I used for the initial PoC demo belongs to one of Jason Smith's FTI puzzles (Radiolarian 1
). The centers of the Icosahedron screw into the core but due to the design of the puzzle, they also need to have a thin shaft to hold some pieces above it as well as be exposed at the surface. To accommodate a screw and a shaft Jason cut the part into two pieces. Unfortunately the initial STL had the caps too close to the body of the part and they fused. I'm testing with the fused pieces.
I have a pretty big graveyard of WSF pieces to test with
