Agreeable Sheep

This is a 3D-Printable "Agreeable sheep" What's an "Agreeable Sheep?" Look here: https://www.google.com/search?q=agreeable+sheep My son is making one as a group project in his 8th grade TechEd class. I thought it might be fun to model one up and print it out. Sizes were all figured by eyeball, and trying to be aesthetic. There's a slight problem with it, in that turning the crank clockwise will cause it to jam, but turning it counterclockwise works fine. I understand what the problem is, but I don't see me doing anything to fix it. After printing, I needed to use a #60 drill bit to clean out the connector holes for the connecting pins. For the pins, I used short cut-off lengths from the legs from some electronic components (20 mil diameter)
