Getting the collapsible ladder out of the way to de-clutter the garage was another small 3D printing project that worked out fine. I designed the hook around the plastic dowels and screws I already had and created a straightforward design to work on my ladder. Probably it will work on other ladder models too. Or the design can be used to be modified to fit other items.

I printed 2 of the hooks that have been designed in Fusion 360. For strength I used a 50% infill with a 200mil resolution.
