Case for elastic cable hooks

This case is to prevent bungee cords from getting tangled up when not in use, due to exposed hooks.
It is made up of three parts: a two-place housing, a cylinder which passes through the housing and blocks the two hooks and finally a threaded nut to stop the cylinder.

note: if your hooks are bigger at bottom and not fit well in the two-place housing, you can easily enlarge the model in slicer (120% should be ok) only in the sense of width, so the internal spaces will be bigger :-)
