Prusa XL Left and Right Carriage With Gates 20t Idlers 3mm

Prusa XL carriages that have the Gates 20t 6mm belt 3mm id for prusa for where the belt touches the toothed side of the belts. It should make the belts last a lot longer in theory. I would install this mod with this one as it does require a lot of disassembly anyway. https://www.printables.com/model/683762-prusa-xl-modified-corexy-back-parts

Reuse all of the old parts and put these idlers in its place https://www.filastruder.com/products/gates-2gt-idler?_pos=1&_sid=1d42bf29e&_ss=r&variant=32673878442055 (the 6mm 3mm id for prusa one).
