My grandma's old stand mixer got jammed up and finally broke. Inspection revealed three gears with broken teeth, of which two were identical. Using Fusion 360 and my trusty calipers, I recreated the gears. One of the gears was also the part that holds the beaters, so that took some iteration to get the right fit.
Unfortunately I didn't take any pictures at the time and the mixer is now gone, so I can only post images of the parts from Fusion 360. But it was something similar to this picture I found on google.
