generic strong wall hooks

Generic wall hooks with 2 eye-holes for screws. I print them on their side with supports and the resulting hooks supported more than 50 lbs on the 'reinforced' upper, as well as 25 lbs on the lower without any deformation, separation, or failure.

They were printed on my ender 3

- 215 -> 210 after initial layer.
- 0.2mm layer height
- Fan @ 30%
-33% Gyroid Infill (which I use on almost everything)
