Have been searching for an organizer and storage solution for my dozens of nylon and leather NATO-style watch straps. This is a 1x4 Gridfinity item that holds 3 straps, with a hook at one end for the strap buckle and a friction clip at the other end. Straps can then be looped around the clip, back towards the buckle, and threaded through the keeper.

Also, props to Lev Mishin for the GridfinityGenerator add-in on Fusion 360 that instantly created the needed base for this item.
