CR-10S4 Round Illuminated Light Switch for 2020 Extrusion

I needed a toggle switch for the LED modules I mounted on https://www.thingiverse.com/thing:2881819. After researching, I remixed mimmim's (https://www.thingiverse.com/thing:2479455) single toggle switch housing to accommodate a round 20mm-holed illuminated 12v switch that pushes in from the front. I elevated the height of the case and shortened its length while keeping the depth at 30mm, so the contacts remain unexposed at the back. I increased the switch hole size to 20mm for better fitment. I printed the housing with the front facing down on the build plate; no supports were needed. Initially, I planned to run the wiring down the frame but found a 2.1mm panel mount female plug socket and decided to use it instead. Since I had already printed the part, I drilled a 4mm hole in the left side of the case to mount it; the male 2.1mm power socket plugs straight in. As the switch is illuminated, you need to utilize all three contacts (2x silver and 1x gold) - refer to the included wiring diagram for guidance. The switch should be oriented so that the gold contact is at the bottom of the housing; I then mounted the side panel mount socket with its longer contact towards the bottom gold contact of the switch, bending it carefully downward a bit with long-nosed pliers. I wired as follows due to the space available inside the printed housing: 1. The "+" of the panel mount socket (short one is positive) was soldered to the middle silver contact of the switch. 2. The "-" of the panel mount socket (long one is negative) was soldered to the bottom gold contact of the switch. 3. The "-" of the LED light module was soldered to the bottom gold contact of the switch. 4. The "+" of the LED light module was soldered to the top silver contact of the switch. The SKP file is also included, allowing you to modify the holes and other features as needed. It turned out well and works perfectly.
