4:1 Rome Gear

Edit: I've added a re-done gear from Gearbox 2.0 which should actually pass skeinforge. The script to use for gear generation is this one: http://www.thingiverse.com/thing:390 because it generates the *entire* gear for you instead of a single tooth. This is important because using array modifiers to create the rest of the gear generates stray edges, which can be nasty to fix and prevent skeinforge from being able to use them.

I'm working on a gearbox in Blender, using the script here:
