Its a simple pulley system. Cable tie or support added to it. I got the idea from this person and borrowed some of his idea, but i improved it some more considered his design is ment for finer printers. My machine couldnt handle it and the Frame got to small and thin and couldnt support the weights put on it. Credit to this guy: https://www.thingiverse.com/thing:532546 for the idea of the pulley itself. The Cableties i designed myself, but i use it for hanging the pulleys on. Can be used seperatly for cables if you want to.
