UK Single socket spacer

Easily add 4.5mm to a standard UK single socket, useful for adding space when wiring is tight.

Allows mounting of Sonoff zbmini outside of back box, especially useful for metal boxes or where space is too tight for safe wiring.

I recommend using self extinguishing/flame proof filament. 

Make at your own risk and consult a qualified electrician before installation, I take no responsibility for this design or it's implementation.
