I got bored, and looking at my desk is a mess. But why go to a store when I have a 3D printer and CAD software?

Probably best to print this in some kind of flexible material so that it can be bent slightly to let the cable in.

Will update dimensions once I've had a chance to print it, or based on your usage.
