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.IMPORTANT - If you see a red exclamation point (!) in Customizer, the STL will not be created correctly! Please adjust settings and try again.One thing for two species!Shell (for hermit crab)Shell (for person)Slice (for person)NOTES
