Somehow the power switch mounted on the side of our Bunn coffee maker got turned off. A minor annoyance, sure, but when you want coffee waiting 10 minutes while the boiler heats the water back up is very annoying. My wife half-jokingly mentioned to print a guard for it. So less than 10 minutes in Fusion360, 20 minutes on the printer, and a small bit of super glue and it's fixed.
The outer dimensions are 35mm wide x 22.69 tall x 15mm deep to fit the escutcheon around the switch perfectly. I made the wall 3mm. My finger can still easily turn the switch if need be, but I never really need to.
Could work for any sort of switch you just need bump protection from.
Provided the F360 file if you want to modify it.
Printed on my Ender 3 S1 with Overture PLA
Cheers.
