Like many makers, [Chris] has a Panavise Jr. on his workbench that he uses for just about everything. The tiny vise is great for all sorts of tasks, and is often considered an indispensable tool. The only problem with the vise is the amount of time it takes to open and close the thing.
[Chris] estimates that it takes somewhere between 2 and 3 million turns of the crank to move the vise’s jaws from fully open to the fully closed position. He figured that his drill is far better at mindlessly turning circles than he is, so he sat down and designed a bit in Google Sketchup to spin the vise’s crank knob.
He fired up his MakerBot and printed out his first “Speed Winder” drill bit. It was decent, but he thought it could be better. After a handful of revisions, he was finally happy with the results. He says it works great, and has posted the model on Thingiverse so that everyone can print one of their own.
