The GPX under-cabinet radio that we have in our house has a power button that's held in place by very thin bits of plastic which eventually break (in our case, after 7 years).  This printed button replaces the original button.Break off the little tabs that held the original button so they don't get in the way.  Put the button in and get it aligned, and screw the PC board containing the switch back in place, and reassemble.The SCAD contains the code from https://www.youmagine.com/designs/power-switch-icon to make the icon.  Getting the icon to print the first layer properly is a little tricky, so it can be omitted if you want.
