Simple cable clip for under desk cable management. Uses a single small countersink head screw.
NB: I saw something similar on Thingiverse / Printables / etc, but could not find it when I went to look for it. So, designed my own. If I have copied someone else's design, I apologise, it was intentional, but only because I couldn't find yours! LOL!
