I originally printed the model by @Ladamtla, but then couldn't figure out how to put it on top of the switch (now I am guessing you could use double-sided tape), so I added a little lip to the bottom.

OPTIMAL PRINT SETTINGS:

Initial layer height: .30mm

Bottom surface pattern: archimedean chords

Make sure heat bed is cooled before taking off print.

You may need to loosen the top screw a little.
