This lock allows one to lock ethernet cables into recessed ethernet sockets, typically found on PC's, as well as routers and switches etc. that normally have sockets flush with their outer casing.
For printing, infil can be 30%, no supports needed, standard width printing head.
I've also made an improved model with better compatibility, easier removal and with a warning message on the side: https://www.printables.com/model/1069792-ethernet-cable-lock-for-all-scenarios
The author remixed this model.
This lock is the same as the original but slightly less deep, allowing it to lock ethernet cables into recessed ethernet sockets, typically found on PC's, as well as routers and switches etc. that normally have sockets flush with the outer casing. i took approx. 1-2mm off the front of the original
