thingiverse
Not a thing really but I didn't figure out how to attach files to a Makerbot operator's group entry.
I came across a nice Processing scheme at http://pycam.sourceforge.net/ and added some more 3D printing related apps with hyperlinks to the projectpages.
Frequently asked as what software to use, this may be of some help. If you find your favorite app missing, add it.
