I modified a basic single gang wall switch cover from the Wally Customizer with some labels for use as an emergency furnace shutoff switch cover. Remix of: http://www.thingiverse.com/thing:47956The STL's likely need to be oriented in Netsfabb, etc. I have not printed them yet, but intend to print on it's back with support - the support junk will be hidden behind the switch plate in use. I plan to switch filament from red to white just in time to make the raised lettering stand out. Alternately, just paint the raised letters in your chosen color.
