Renforced hook

This is an renforced hook. I couldn’t find a renforced hook on thingiverse so i decided to design it myself. I don’t know the strength of the hook but is over 5 kg.
I tested it with a full basket of cherries in my tree (the first objective of this design) and I tested it with a heavier load such as a wooden chair. This hook can withstand a minimum of 7 kg.
There is two designs, the second one has a longer hook.
It is possible to print this part with a variable height to increase or decrease the resistance.
The force exerted on this hook is a shearing force. To avoid any problems with mechanical strength, I recommend choosing a triangular filling, as this type of shape is best suited to shear stresses.

If you have any new information on the weight that the hook can support or on the strength, let me know, I'm curious.
