replacement car window crank

thingiverse

A friend needed a Miata window crank replacement, so I designed one with rounded edges and curving splines for compatibility with many manual car window cranks. To fit my MakerBot, I shortened it compared to the original design; the handle can be easily enlarged in Solidworks. Print the part, get a clip from a store, install it, and profit! The "testpart" within the design was a block with the gear inside, made to test the window-moving teeth function on the MakerBot before finalizing the full part.
