Kitchen Mixer Adapter

thingiverse

I'm having trouble with my Aldi Mixer, and I think it's actually made by Bosch. The problem is that the adapter plate broke, so I need to get it replaced or fixed. The broken part has an inner rod with a circumference of 7 millimeters, and the flat section has a diameter of 5 millimeters. On the other side, there are indentations for gripping purposes, with a diameter of 16 millimeters. The outer circumference of the adapter that matches up with the mixer is 20 millimeters.
