Three Part Bosch Universal Mixer Spur Gear Removal Tool

thingiverse

My wife and I were discussing our Bosch Universal Mixer and wondering how we could clean under the spur gear. I figured I could print a tool to engage all of the retention clips and was glad to find [davidhbrown](https://www.thingiverse.com/davidhbrown)'s design ([2833870](https://www.thingiverse.com/thing:2833870)). Unfortunately, it needs to be printed vertically and I had trouble with layer adhesion. I reused a lot of [davidhbrown](https://www.thingiverse.com/davidhbrown)'s [design](https://www.thingiverse.com/thing:2833870) but separated the fingers into three thicker slot-together parts that can be printed flat--improving strength and printability. No supports or cleanup (other than stringing from my printer) necessary. They slot together right off the bed. Please see [davidhbrown](https://www.thingiverse.com/davidhbrown)'s [design](https://www.thingiverse.com/thing:2833870) for instructions for removing the spur gear. In any case, we were horrified by what had been hiding under the spur gear of our bowl (let's just say that black contrasts strongly against the white plastic of the bowl and gear). After removal we did a lot of scrubbing of both the gear and the bowl. We will be using this regularly now to prevent repeat buildup.
