I have a Cuisinart SM-50 stand mixer and it stopped working properly after a few years. It felt like a “clutch” with the mixing part not spinning while the engine was speeding up.
One gear in the main gear train is made of plastic/resin instead of metal. I could not find any schematics or replacement part online for this model. Some might say it's on purpose so you have to bring it to a Cuisinart specialist…
Anyway, I managed to isolate the specific issue, and modelled this replacement part. I printed it in PETG with 100% infill, and the mixer works perfectly now. I'm uploading this part so it could be useful if you want to save some money.
Print parameters
- PETG recommended
- 100% infill recommended
- 0.28mm layer height
Files
- The raw file is a perfect fit, with no tolerances. You might have some issues depending on your print
- The 0.2mm offset is the one I used for the fix and it worked perfectly in my case
