UK Double Plug Shelf

I have several Orbi routers around the house and found that I always had issues with where to put them. My main issue was that they were never close enough to a plug socket to be able to be displayed properly. This shelf can be used for several devices but I mainly had the Orbi routers in mind when designing. Because of this I have designed a simple plug socket mount that goes behind a UK double socket and adds a cable hole so the plug is tidy. In order to install this you need to remove the double socket which involves messing with electrical wires. Please only do this if you are competent and know how to isolate the supply first.
