Panel mount Cable holder

Simple cable holder that can be screwed to any surface.
I designed this to organize my audio cables under my desk.
The nice thing is that you can fit the cable through the opening shape, but then it's impossible for it to detach unexpectidely.
You can fit cables up to 7mm diameter (audio cable for instrument or speakers), maybe 3 or 4 of them.

Screw used are countersunk 3.5mm diameter.
