I bought a small amplifier for the video game audio. I want the controls of the amplifier to be accessible from the outside of the arcade machine so that the volume can be adjusted, and so that you can plug in headphones. I decided to locate it in the panel below the control panel, roughly where the coin slot was in vintage games.
I needed a way to way to mount it, and I came up with a design in Open SCAD.
This design allows me to cut a hole in the panel that is only slightly larger than the amplifier, and screw the bracket in from the inside of the cabinet. In order for this design to work, I needed to remove the rubber feet on the amplifier.
Luckily, those were just stuck on with some adhesive. Here are some photos of the printed bracket and amplifier.
The bracket covers the “line out” connection on the back of the amplifier, but I won’t be using that, so it’s not an issue.
