I recently had a need to mark and color code about 200 ethernet cables for work. The products I found in on-line stores were kind of expensive and a little bit painful to snap on, so I designed these. They clip on and off fairly easily, just hold both sides of the cable and press it on with your thumb. I made them in 5 different colors of PETG, and now I know at a glance what VLAN my cables should be assigned to.
