Prusa i3 MK3S Top Button Board

I wanted to have a few buttons to control my printer without having to work my way through the firmware menu or having to pick up my phone to connect to OctoPrint. In my case, I wanted to have a panic (pause) button, a button to auto-home the nozzle, one to eject the filament, and a few for temperature presets. The button board snaps to the top bar of the MK3S. I'm using six shiny metallic 12 mm buttons from Amazon and wire them up to some of the GPIO pins on the RPi. The OctoPrint Physical Button plugin then provides an easy way to assign actions to the buttons.
