Thanks for the positive feedback Po! Greatly appreciated. The push-button I chose is a UR168. I have used these in my industry (nuclear) and really like the look and the haptic feedback they provide when pressed. The internal LED (if you decide to use it) is 12-24vdc.

Let me know if you would like two of the 3d printed inserts. More than happy to print some off and send them your way.
