This is a door release button for a Panasonic NNSD277B/W microwave.

I bought the microwave a little over two years ago. Since then, I've had both plastic retention tabs at the side of the button fail, and ordered a replacement part.

After a little over a year, one of the replacement part's tabs has already snapped off and the other is sure to follow soon.

I decided to reverse engineer the part in FreeCAD today before the other tab breaks off (they get lost inside the microwave making them virtually impossible to retrieve) and share it here in the event I need to print myself off a copy at some point in the future.

Panasonic: Shame on you for designing such a crummy part and charging your customers ~$50 to replace it every ~18 months.

For production with a 3D printer or 3D printing service.
