Cable keeper ball

This is a simple little ball I made to hold some USB cables up, so they don't fall down through the cracks in the side panel of my couch. The inner bore is 5mm across, which is big enough for most USB cables, and allows the cable to move somewhat freely back and forth. This does not clamp down hard on the cable. Needs two M2.5x10 screws and 2 M2.5x3.5x4 heat-set inserts
