This is a single shoulder trigger button for the Anbernic RG35XX H Handheld. I found I didn't like the double shoulder buttons and just wanted a single shoulder button for my SNES and GBA emulation.
To swap out the button, you'll need a hex bit and a plastic pry tool to open the case. Once you have it open, you can just slide the old buttons off and put the new ones on.
This isn't a completely polished design. I created it on a whim and got it to a point where I was happy with it.
