Having your home or office kitted out with cat5 or cat6 networking cables is pretty much de-rigueur for any self-respecting geek. However, sometimes the sockets you fitted into walls and floors aren't as accessible as you'd like.
Inspired by some hotels I've stayed in, I designed and 3D printed the Desktop Network Socket. It's essentially a nice looking "back to back" connector. Not much real electronics involved but I thought you might like it.
