Fun project with my 7 year old. Tinkercad it to fit your situation if you'd like. Fits a Proctor Silex "durable hand blender". This ended up being a terrible print for me in PETG, but I just dont have my settings right yet. I used 3mm walls to make sure it make the small attachment to the cabinet solid.
