GE Profile Microwave Oven - 3D Printed Turntable Wheel Repair
With the COVID-19 lockdowns in effect we're tapping our frozen reserves of past harvests and prepared foods more frequently. The microwave has certainly seen an uptick in meal prep. Unfortunately one of the turntable wheels on our GE Profile dislocated and became damaged beyond use which prevents rotation while cooking - game over for achieving reasonable cooking performance.
Lengthy shipping delays and complete shutdown of business is the norm at the moment so I decided to 3D print a replacement. With such a simplistic part, reverse engineering one of the working wheels took only a few minutes as did whipping up a model in SolidWorks.
Print took ~15 minutes then snapped on and rotated like an OEM part.
For those in a similar situation, I'm releasing the STL file for fabrication on your own 3D printer - hopefully there's someone out there who's life got a tad easier during these crazy times.

UPDATE: Over time the PETG wheel become deformed due to heat. I switched to ASA which has a substantially higher glass transition temperature and all is well.
