NEC TurboExpress or PC Engine GT Replacement Switch. 3D printed in most colors.

I can't be the only person that was missing one, and these things are nearly impossible to find for obvious reasons. They aren't a perfect replica because some modification was needed for strength, but they look really close when installed and function perfectly.

If you needed another part and I have an original I can use as a model I might be able to design it, but it takes a while and there would be a design fee if it was especially complicated.
