A simple hook to clip onto the back of a table or desk. I initially designed it to hold a surge protector, although it also works great for holding loops of wires. It still looks messy, but it's a clean, organized messy ;-)

The print is customizable through Thingiverse's built-in customizer, or by downloading the SCAD file and opening in OpenSCAD. Parameters have been added to adjust for the thickness of the desk, and size/placement of the hook.
