Instructions To piece this friction hinge together first you will need to sand and file the print. Next you may need to re-drill the holes on the hinge fingers to smooth out the inside of them. Next you will need a bolt that has a shaft with a 5mm diameter and is long enough to travel through all of the hinge fingers, and a nylon locking nut to screw onto the bolt. Before running the bolt, two rubber o-rings will need to be placed on each of the internal hinge finger contact points. These are marked in a figure shown above. Once you have the o-rings and bolt in place, simply place a washer on the end and tighten the nylon locking nut, until the about of friction you need is achieved.
