I am working on a project and I needed an easy way to create an Ethernet jack from a standard patch cable.
I found these cheap RJ45 Keystone Adapters (https://www.ebay.ie/itm/RJ45-Keystone-Jack-Wall-End-Plug-Cat-5e-Ethernet-LAN-Network-Module-Port-Adapter/252314420824) which you can easily wire to a standard Ethernet cable. I needed a way to cover the exposed connections and attach it to the project so I designed a cover for them.
The jack has to be slightly modified in order to fit into my design, two clips have to be cut off as shown below.
I wired the jack according to the Ethernet 568B standard, shown as B on the jack. I cut a short Ethernet patch cable so that I had a male jack to connect to the device I was using and I could wire the other end to the jack.
The cover prints in two parts, the main body and a spacer to cover the gap left by the wire and to hold the jack in place.
The fully assembled cover with the jack can be seen below.
The files for this project are available on Thingiverse (thingiverse.com/thing:3401690).
