Project Shellter - Shell 01

UPDATE 2011-10-25
I uploaded shell-012948.stl, the file as exported from Sage, for shell thickening experimentation. It was mirrored from the original exported file because a hermit crab needs a right-handed shell spiral due to the way its abdomen curves.

Pimp out your hermit crab!

This is the prototype shell for Project Shellter, the current artist residency at MakerBot Industries.

It is modeled on the shell of the Cittarium pica sea snail, http://en.wikipedia.org/wiki/Cittarium_pica, and is similar to the ones that crabs in pet stores typically sport.

It was created using Sage, http://sagemath.org, exported to an STL using a modified version of Christopher Olah's plugin, http://trac.sagemath.org/sage_trac/ticket/7744, and thickened in 3DS Max.

You can explore other shell shapes here http://sagenb.org/home/pub/2928 (account required).

The goal is a workflow using open source tools, but the conversion of the surface to a solid at this point requires a commercial tool
