We're excited and proud to launch Thingiverse Apps. Learn More about what this means to you.
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.
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.
Maybe someone can figure out a way to thicken the surface without 3DS Maxâ€½

This was printed on a Thing-O-Matic with Mk 7 extruder at the world famous BotFarm using Matt's excellent support settings: http://www.makerbot.com/blog/2011/06/27/makerbot-microtip-using-the-support-features-in-skeinforges-raft-tool/
You can print it, I know you can!
Thanks to @JonMonaghan for the 3DS Max-fu, print and photos (my first print failed, and he kindly reprinted it for me so I didn't miss my flight).

So what's this mean?
We're sure TeamTeamUSA would love to see what you've printed - take a photo and share it on Thingiverse as a Make.
To post a Make simply visit this Thing again and click I Made One to start uploading your photo. You can also download the Thingiverse Mobile app (available via Google Play and Apple App Store) to take a photo and upload your Make right from the app!
