This is my take on some switch modules I intended for the use in a Cyberdeck, but ofcourse they can be part of a flight Simulator, for decoration and so on...

The modules are intended for use with standard sized switches. The outer holes are modeled for M4 screws. The Switch-Guard (as seen on the Chemtrails switch) is bent from 1.8mm steelwire. 1.6mm - 2.0mm should work fine, though you might need to heat the bent wire so it can melt away the extra PLA. After that you have to glue the steelwire from the underside of the module (two part epoxy worked best for me).

I included the STLs for the switch modules from the above pictures, as well as a Blank version that makes it easier to add your own labeling.
