Automatic Gearbox Modified Shaft & Crank

thingiverse

I took Emmett Lalish's impressive gearbox (http://www.thingiverse.com/thing:34778) and gave it a physical shape by printing it out. Feeling that the joint connecting the crank to the shaft was unnecessary, I made the bold move of linking them directly together instead. As an added touch, I came up with a removable end stopper that allows for easy insertion from a different direction. Kudos to Lalish for making this incredible design - the minor modification makes all the difference! On certain printers, height can indeed be a problem; I should have mentioned this initially. With some tweaks and refinements, though, I'm confident we can optimize its performance even further.
