    Here is my last version drawing of the rotating ball nuts based on Jonathan’s design. They have two pairs of timing belt pulleys so I can easily change between 2:1 and 1:2 ratios.

    I tried to make the design as compact as possible to allow me to have the screws closer to the gantry/rails and consequently the spindle as close as possible to the gantry rails.

    The three drawings are for 1610, 2510 and 2005 ball screws. Still not sure which ones to use.
