The original oxystele.stl had spiral holes in it. After running it through http://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 http://www.sciencedirect.com/science/article/pii/009784939390054D!
Modeled on the shell of the Oxystele sinensis sea snail, http://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 http://www.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.
Cortie's model and many of its resultant shells have been written in Maple http://www.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 taskÃÂ¢Ã¢ÂÂ¬ÃÂ½
