16014 Bearing – 3D printed

Hey everybody, I just wanted to share that I’ve used the following 3D printed 16014 bearing successfully as a substitute for a metal one. The stepper motor can still easily rotate the entire weight of the arm as it is fully extended horizontally. The bearing does have a slight amount of play, but it seems that it can be mostly eliminated by making sure each roller is as accurate as possible. There are other designs that use metal spheres, and those would probably work best. ;
