Kylie Karshellian adopted a print of this shell today! See it happen here with annotations and music: youtu.be/LtvlLBQnEc0

The original oxystele.stl had spiral holes in it. After running it through cloud.netfabb.com the holes are gone. If you downloaded the file before, please re-download it.
Another one of M. B. Cortie's greatest hits sciencedirect.com/science/article/pii/009784939390054D!
Modeled on the shell of the Oxystele sinensis sea snail, en.wikipedia.org/wiki/Oxystele_sinensis, will Coenobita clypeatus - "Purple Pincher" - hermit crabs like this? Only experimentation will tell!
It was created using Maya's shellNode plugin, which is based upon Cortie's model, and thickened using Blender's Solidify modifier blender.org/development/release-logs/blender-256-beta/solidify-modifier/.
The goal is a workflow using open source tools, but this shell surface required a commercial tool. Thanks to a tip from thingiverse.com/mesheldrake, the conversion to a solid is now handled by an open source tool. :)
Cortie's model and many of its resultant shells have been written in Maple maplesoft.com/applications/view.aspx?SID=3851&view=html. Porting them to an open source tool such as Sage or Blender is the last step in creating a complete open source workflow.
Any python ninjas up to the task‽

Instructions
Some notes:
* You must use support material, and it's not as difficult as it sounds! Matt's excellent support settings work great: makerbot.com/blog/2011/06/27/makerbot-microtip-using-the-support-features-in-skeinforges-raft-tool/
For convenience, they are available here for Skeinforge 35: dl.dropbox.com/u/39152244/SF35-Thingomatic-HBP-Mk7-MG-Support.zip
* For printing, you only need the oxystele.stl file; the other file is just a surface and is provided for thickening experiments
* Printing with the aperture facing up and the shell parallel to the printing surface yields the best quality hollow print so far
* Once printed, the minimal support material is easily removed and the entire shell is hollow
* Sanding or tumbling to smooth the surfaces is optional but recommended
You can print it, I know you can!
Go!

Hi, this gives me an idea.
Some people have pet "hermit crabs" in aquariums, that use any shell-shaped objects to hide and must regularly change them as the grow.
Why not make funny looking shells for them like pokemons, knight helmets or human faces, but with the same spiral inside so the crab can hide?
You mean like this? :)http://vimeo.com/49111005
They printed those in ceramic, though. I don't know a hermit crab would go living in ABS.
You could also make them a regular shell but with added racing stripes, rocket engines, license plates, and other such fun stuff.
