Here's a basic cable clamp for securing a cable to a stud (or whatever you want to screw it in to). The screw hole was intended to fit a drywall screw, but other's should fit fine. I made this for helping-square up ethernet cables run in my walls.

This was made with CAT6 cable in mind, though in the example make, I actually used it to secure cabling for a camera.

There is a dual cable version of this design available here: https://www.printables.com/model/431053-dual-ethernet-cable-clamp
