IKEA Algot hanging clip for unused frame rails

In order to use some of the dead space at the right-hand side of my Algot storage racks, I figured I needed something neat that clipped to the rails I wasn't using (as the deep bins only use every other rail).

As such, tada. Clips on to the rail neatly, and holds small-ish weights. I'm using it to keep some of my boots out the way, which may be a bit of a stretch, but whatever works for you.

Edit: There's also a mirrored version for rails on the left-hand-side, IKEA Algot Rail Hook Left-hand.stl
