Very interesting design!
Would it work on a metal ball screw? ball nuts are the costly parts...

Originally, I machined a version of this ball nut out of acetal and used it with steel balls and a steel screw. I suppose that if you printed this out of ABS and did a light vapor smoothing, you might be able to do the same thing. I kind of doubt, though, that a 3D printed version would ever be smooth and accurate enough for many real applications.
