With the thread generator, Screw top containers are not rather automatic, but they are close.
This really is uploaded more as an ad of the screw thread script-- rolling one's own containers ought to be pretty much a breeze with it!
Note Nophead has printed the layout as it now stands and the screw cap does not function! I have uploaded a fresh variation, but until we get evidence the fix worked, Nophead's field tested layout is here: http://www.thingiverse.com/thing:84
Edit: Added the Blender file. This ought to allow it to be even more easy to scale this model to whatever size and height/diameter ratio you would like!
Print it and use it! Single STL file matches in the MakerBot place, although maybe you had get lots of stringing if you only printed these collectively like that...
