Small cup/coverage/outlet cover

In my flat there is a power cable at the middle of the wall. Was used for a wall mounted lamp before, but got no use for me.
So I wanted to cover it for aesthetic and safety reasons, but with the premise to be able to utilise the power cable in the future.
Made this small cup out of white abs, positioned it onto the (previously well isolated) cables and glued it on with some painter's acrylic.
Afterwards just painted it with the wall paint.
