I needed something to run cables along our drop ceiling rails in a way that I could easily remove them. The first few cable clips I found looked great, except that they were obviously intended to hold the cable securely without any real way to put it up and take it down again. So... this is what resulted.

Printed in PLA with a 0.4 nozzle, it seems more than strong enough to deal with the cables I wanted to run (the main cable for an Oculus Rift S, for the record) without having any problems at all. It bends a little, but so far none of them have shown any sign of breaking, and when they do, it's pretty much nothing to replace, so I'm pleased with it.

(Edit/Update mostly adding the picture - ended up getting some retracting holders anyway but they worked great for that too)
