The button uses a standard 20mm limit switch, Kw4-3z-3 Micro Switch, Kw4 Limit Switch, 3-pin N/O N/C switches, and an optional common 5mm LED. If you have access to a resin 3D printer, I've included an extra STL file, "pin 2." Use a 0.05mm layer height for this one in case you don't want to use M2 16mm screws. I've also added a picture with dimensions in case you have a similar 20mm limit switch model.

The button is designed to fit into 1.25-inch holes and up to a thickness of 0.5 inches

You can 3D print all files at a 0.2mm layer height, except for:

"Push button with LED.nut" – Use 0.1mm layer height for this one
to ensure the nut slides easily onto the threads
"Push button with LED.Pin" – Use a 0.1mm layer height and a 30mm/s print speed. Try not to overheat the nozzle to ensure a smooth finish.
You may need to sand the ".Body" and ".Button," depending on how close your nozzle is set to the heat plate and how well your 3D printer is calibrated.
