Sharp SMD2470A Drawer Microwave Wheel Axel

Sharp drawer microwaves are known to have an acquired issue where either abrasions on the metal wheel axels or paint damage on the drawer frame from the wheels or wheel axels creates severe current arcing in the microwave.  Sharp denies this as an issue but settled in a class-action lawsuit for 114 million dollars.  If you were not aware of the lawsuit or experienced this issue after the lawsuit, you will unlikely receive support from Sharp for this issue.  It's an expensive and difficult to install microwave and this is a dangerous problem to leave unfixed.  

I was able to remove the metal wheel axel from the affected corner with needle-nose pliers. This revealed the areas of exposed metal on the frame.  I used a high-heat resistant spray paint ( you can get special microwave paint, but good luck finding it in black) to cover the scratches.

This should be printed in ASA or something similar without supports with 100% infill.  

Apply a small amount of mineral oil to the tip and use needle-nose pliers with one tine on the axel wheel and the other on the frame to push the axel head through the frame-hole.

This model was not tested on animals, but a mouse could probably use it as a butt-plug.
