Strong clip-on hook for wire shelves

thingiverse

This is a larger, stronger version of my clip-on hook designed specifically for standard wire shelves. I was able to hang a 35lb kettlebell from it without it breaking, as the photo clearly shows. However, I do not actually recommend this for hanging extremely heavy objects. My guess is that very heavy objects will eventually fatigue and break PLA (my current material), and drop said objects, possibly causing damage or injury to anything/person underneath. The shelves these are designed for are widely available in hardware stores, Sam's, office stores, and other similar retailers (see photos showing shelf). I deepened the snapping mechanism a bit from my previous design, so these fit very snugly with a satisfying "snap." They are also removable and easy to use. The primary force from anything that hangs from them is vertical, whereas horizontal force at one of the clips is needed for removal.
