I made this model to solve the problem that I have, too many small and hand driven screw bits. When working on my 3d printer (or any other items with small screw sizes) I often get hand cramps and have to take a break, so, I decided to make a ¼ screwdriver adapter to work with my small screw bits.
Works with 4mm-3.9mm hex bits
Print with 100% infill and 3 walls, i found it best to have the seams be aligned towards the back.
