Summary

These hooks are quick to print and easy to use. I printed them for the ip cam cables outside my house. Can be used indoors as a wall hook or to manage cables.
The hole diameter is approx 8mm , so any wall screw size 5-8 can be used to mount these clips.

The clip can be printed without support, if its placed on one side as shown in the cura screenshot.

I printed mine using PETG 0.3mm layer height and a 0.6mm nozzle and set wall count as 3. Increase the wall count if using a 0.4mm nozzle so that the part stays sturdy.

These hooks have a snap closure, if you are interested in a version without snap closure , please refer to my other design : https://www.thingiverse.com/thing:5572963
