USB Extension Cable Desk Mount

My USB extension cable kept falling behind my desk so I created a movable desk mount for it. The mount is universal so if your USB extension cable fits but loosely you can tighten with screw on top.

The USB cable hole dimensions are:
Heigth = 12mm
Width = 20mm
Depth = 40mm

The desk thickness can be 25mm max, larger will not fit, smaller will as you can tighten with screw.
