FOR USE WITH KentO's BOGIE IDLER ONLY! Big thanks to him, because his main plate and idler solved all my FLEX filament issues on Prusa MK4S.

Hi, this is modified one part of main plate for Prusa XL. It is part of KentO's model placed on XL main plate. This replaces Main_Plate_9_R3.stl and Main_plate_10_R3.stl.

For the rest use KentO's files:

  • Idler 1-2
  • Idler 6-7

Or you can use Idler with more pivot: https://www.printables.com/model/1365827-mk4s-xl-core-one-bogie-idler-with-more-pivot

Note that for installing main plate, it is better to loosen and slightly pull out the nextruder nozzle.
