Three Part Bosch Universal Mixer Spur Gear Removal Tool

thingiverse

My wife and I were discussing our Bosch Universal Mixer, and we wanted to know how we could clean under the spur gear. I thought that printing a tool would engage all of the retention clips, so I was glad to find Davidhbrown's design on Thingiverse. Unfortunately, it needed to be printed vertically, and I had trouble with layer adhesion. I reused some of Davidhbrown's design but separated the fingers into three thicker parts that can be printed flat, which improved strength and printability. No supports or cleanup were necessary, except for stringing from my printer. They slot together right off the bed. Please see Davidhbrown's design on Thingiverse for instructions on removing the spur gear. We were shocked by what had been hiding under our bowl's spur gear (let's just say that black contrasts strongly against white plastic). After removal, we scrubbed both the gear and the bowl thoroughly. Now, we will use this tool regularly to prevent buildup from happening again.
