About this 3D model

Simple wall hooks to hang a picture or anything else. 3 sizes for different screws (4mm, 5mm, 6mm). The smallest one can take 10kg weight(tested with PLA) but I would go with 5kg max to be sure. Print with perimeters only. I recommend 0.12-0.16. layer height for maximum strenght. Print on its side. No supports needed.
