This is a new screw design which will fit the Gravitrax Motorized Marble Lift www.thingiverse.com/thing:4178353 and is not a remix, it is a complete re-design. I kept the same pitch angle and used the taller height. I found that with the original design, the balls would not enter the lift and that the screw itself had a problem printing cleanly with the overhang all the way up. I hate using supports and so I redesigned this one to print without any. I also re-designed the inner bits so that it is easy to align and I added a conical top, once again to avoid bridging. This one prints beautifully and I really want to thank ffleurey for his wonderful work in making this thing for all of us to use. I am thrilled that I didn't have to do all of the work on the lift body as his design is brilliant!
I have remade the old style motor hub as it was pointed out to me that it has been changed to a version that no longer works with this screw. This hub is like the original or at least as close as I could get and should work with the screw. Thank you XXV for letting me know that things had changed!
