Screw Shelf Support

Wanted to hang a shelf in my studio wall, saw some examples online utilizing pistons and after a few days had the idea to model giant screws, that would themselfs fix onto real size screws. Couple of days later… tcha ram !! Here is the Screw Shelf Support, a giant screw that you fix into a real screw in the wall and screw into a plank of your choice, I used some leftover wood I had from some pallets. I designed this model to fix onto 6mm screws that have a 12mm head (you can see these screws on the wall in a picture) and I would suggest printing just the screw end separatly in order to test if it works with your screws, different printers may produce different results. If something requires changing, the STL file is available for a single screw, which you can then change and print freely.
