KitchenAid Attachment Knob

My old accessory knob for my KitchenAid cracked on three sides up the height of the part. I found TheiaD's part, but it wasn't the correct dimensions to the original knob and was too loose on the metal pin for my KSM90WH (300 Watt, 4.5 quart). Great starting point though, thanks Dimitri.

My I3 MK3S prints dead on, therefore this part was designed to be identical in dimension to the original and was printed without modifying dimensions.
