This is designed to hold a small momentary push button switch and two USB headers to allow external USB ports on my bartop arcade machine.

The plate is designed to mount in a 57mm hole on the rear of the machine and is screwed to the inside face with wood screws.

This could be printed in any material, I used PETG.
