Hook for IKEA Raskog Utility Cart. Tried many others 3D printed hooks, but they just aren't robust enough for heavier load like fully loaded backpack. So I made mine! And I thought let's just share it.

3D printed and even plastic Cart hooks are prone to cycle fatigue, and with 20+lb of load, it was good for the hooks to last for more than 3 months. This design attempt to handle the load by 1) thicken the hook and 2) add an additional load path with the little protrusion in the bottom.
