This design needs 2 bearings as well as 6 hex nuts. I've being working on this weigh too long, because this trend is gone, but if you want this you may . I designed this fusion 360 over the coarse of 4 months because I didn't have a 3D printer to trial the files, but now I do. This helps me out a lot with school and building my dream 3D Printer.
Thanks a heap XD
