Cupboard Hook for ELFA system

thingiverse

Having an ELFA storage system at home is definitely a nice feature, but getting new parts can be quite costly. A simple hook seemed like a practical solution, but paying $1 or more per unit seems excessive. I designed this hook to hold my backpack and other items, fitting snugly into the available slots. After the first prototype showed some flexibility issues, I reinforced it and now it can easily carry 5kg of weight. To make it printable without support material, I had to carefully break out the two thin walls between the hooks. I've uploaded two STL files with slightly different hook designs, one with a 16mm and another with a 19mm spacing option, in case someone needs to fine-tune their own backpack handle.
