Improved Headrest Hook

I downloaded the original print in place model. It printed good but my daughter kept breaking off the little pivot pieces for the links. (Totally my fault for not getting the print settings right for ABS) So I redesigned this with links you screw together for added strength. I also shortened the item hook to make it look a little better. I printed 4 of each link piece to make it the same length as the original. The holes in Link C are sized to cut the threads while assembling. You may need to run a 3mm drill bit through the holes in Link A depending on your printers tolerances. Notes: I recommend printing in at least PETG. ABS/ASA would be better. PLA will most likely not hold up in a hot car in the summer. The hook will need supports to print correctly. It is in the best orientation for strength on its side. You will need: 9 - M3 x 22mm Screws (one commenter said he needed 25mm screws but 22mm worked for me)
