Braun mixer axle coupler

thingiverse

The part in question is the axle coupler of a Braun hand mixer. My guess is that it will fit several different mixer models from Braun, although I'm not certain if it's compatible with other brands. Measuring approximately 12mm x 15mm, this component features a square hole on its inside surface and an axle form on its outside. Given that it never comes into contact with food, food-grade certification is unnecessary.
