I rent spaces and prefer to avoid causing damage that I'll have to repair later, so I designed the Shelf Hook to clip onto existing shelves. This is the second iteration, with a modular design to allow the clip to be tightened to make it a bit more secure when clipped to a shelf. As with the original, the hook pivots freely, allowing support items to be adjusted and hung at needed angles.

In this version, the hook mist be threaded through the hookPlug, which can then be screwed into the base of the clip. The plug should still remain a bit loose until the clip is slipped onto the shelf bottom. Twist the plug to tighten the clip, securing it further. This is printable on resin and FDM prints in any sturdy material.
