The threaded bolts as axes for the X and Y idlers are, in my opinion, Prusa's biggest design flaw. It shortens their lifespan too much. Here is an alternative for smooth axles. I used 3mm spring steel rods and shorted them with a Dremel.…
During my fight against breaking idlers i slightly modified the x-axis to achieve better alignments between rods, bushings and timing belt. A T20 GT2 idler and a 3x18mm dowel pin as axis are needed.
