One of the hassles of my MakerBot is having to raise and lower the z-stage (the up-down platform holding the plastic extruder) by tugging on the rubber belt. Tug, tug, tug, just to get the extruder into the right position for beginning a print. Zaggo in the Thingiverse made a printable crank to solve this pesky annoyance.
