No, I am not a fan of lm8uu's so I doubt I will ever make the effort to convert the parts, though others may do so or you can always mix and match parts with LM8uu poieces from thingiverse (the X ends, X carriage, and Y axis are all compatible with Prusa-compatible parts).

This topic seems to be coming up more and more lately, not sure why. I recommend at least starting with the recommended bronze bushings. Unlike LM8UUs, bronze bushings are completely maintenance free. They are smoother, quieter, cheaper and lower maintenance.

LM8UU's are beneficial when you are m
oving a very heavy load. Sliding resistance vs. rolling resistance becomes more of an issue if you are moving a large weight. For the loads we are moving, there is no benefit and a significant number of disadvantages.
