Stronger wall-hook

Here's a 2-part hook for safely hanging kitchen pans, or other 'heavy' things.
-Use a single M4 screw. Also, I included a small hole at the bottom of the hook for an optional "finishing nail" (-diameter ≤1.5mm) to help prevent rotation.

-Please note that the bottoms of each piece are designed to interlock with each-other, and thus will hold firmly in place, once installed. (-Refer to the picture above.)

--> I would like to do more with this design, but right now I feel I just don't have so much time to devote to such a small project.

For this, I simply wanted a stronger hook than most. The better (i.e. stronger) way to print a hook is with it lying on its side. -But then what about a back-plate that keeps it from twisting?..... So, this is what I arrived at.

-Will update/change later, maybe.....
