Keyhole Hook for Metal Shelving Units with 1/2"x1/4" keyholes

thingiverse

UPDATE: Added keyholehookv2.stl, which fits much better and is slightly redesigned to accommodate even more weight at any infill. Please download this model instead of the deprecated keyholehook.stl (leaving for now, but will later delete due to inferiority versus the new version). I whipped up a very simple hook design to fit in various metal shelving units that have 1/2" x 1/4" keyholes on support bars. These things realize a lot of storage potential for otherwise unutilized space on your shelves. They also print very quickly (under 10 minutes at 20% infill) and are quite robust. As you can see, they are capable of supporting over 2 lbs. at just 20% infill (that scale tops out at 850g, and the driver set exceeded that limit by at least 150g in my estimation). I'm sure they could hold quite a bit more at a higher infill, but I have not tested this. Hope they help you out!
