I was growing tired of seeing a coiled up pile of cable on the floor below my lighthouses, so I went through several iterations of covers and settled on this version. There is a small channel to run the cable out the bottom (for example, into a cable channel like this one from @Leon_H that I printed as well), and the cable itself can be wrapped around the inside chamber with everything tucking up flush against the wall over a North American outlet faceplate (approximately 120x75mm).
One downside is that on a North American outlet for this cover to work, the power plug needs to be plugged into the top outlet for it to fit properly, which does prevent the use of the bottom outlet with this configuration. For me, I have plenty of outlets around my office, so this isn't a problem, as I made this mostly for the aesthetics of hiding and managing cables. However, if you are short on outlets, you may want to consider a different option or remix this to fit another way around your outlet.
