Shoe Rack Shelf Stabilizer Bracket

Threatened with the specter of destruction by falling shoe rack, I envisioned tying the thing to the wall for stability. The rack sellers claim a capacity of ten's of pairs of shoes, so keeping them from tumbling down would certainly be a good idea. So, the design is a swinging arm that comes down to clip on the shelf rods, thereby keeping the shelves from tilting away from the wall.

The design is print-in-place, 0.5 mm clearance. I found it to break free pretty easily, no supports required.
