I had the misfortune of getting a stirring tool caught in the mixing mechanism of my Cuisinart Stand Mixer, which then stripped out the plastic Helical gear in the drive system. I'm sure it was made in plastic to do such a thing, but there are no replacement gears available ANYWHERE! This post is meant to help people who have had this happen to them. I have created an .STL file that can be sent to a 3D printer (or 3D print shop) that will give you a replacement part and get your mixer up and running again.
