About this 3D model

Why should only hermit crabs wear a shellter? Now both crabs and people can enjoy Oxystele sinesis "heart" shells! Create a customized home for your crab, and a stylish necklace or earring for you that reveals where another species lives. The Customizer is the missing piece to enable a hermit crab caretaker to make the correctly sized shell for a crab. A Sage (www.sagemath.org) version has been in development, but when the Customizer was announced, development shifted to this thing. This is a first version; other versions will be forthcoming. Please use and report any issues in the comments.
