z axis drive screws

I have started to put together 2 gt pulleys and put them on the top of the z axis screws and join the two screws together with a gt2 belt and bearings with housings to hold them in the correct alignment and only run 1 stepper motor to drive both screws and hopefully stop the creep between the 2 screws which is the biggest contributor to have to level so often
