Screws for the Corsair Crystal 570X I printed because I lost mine. I used PLA+, 100% infill and a .6 mm nozzle with .15 layer height but a .4 will probably be better. They are Just M4 screws with the long one being 28MM and the small one is 7.5MM with a 5MMx13MM head. i wouldn't screw them in to hard because the threads are very small with the small screws all the threads are used but with the long ones only 1-2mms are used.
