I used the parts from this kit https://www.printables.com/model/3267-led-light-bar-prusa-i3-mk2mk3 to mount the LED lights on the lid of my Original Encloure. Then I mounted the on/off switch inside the Prusa Basic Board Cover.

Board Cover printed at 0.2mm layers in 2 colors at 0.6mm and 1.2mm changes, all in PETG.
