I created this clip to organize some cables on my "video studio" aka home office.

Just screw it to a wall or any other surface and you can thread a bunch of cables through it. The gap between the two hooks allows for addition and removal of cables without having to deal with the plugs. At 100% scaling, the diameter of the smaller hook is 15 mm and the bigger one 20 mm.

Simple print, PETG recommended for elasticity.
