MMU2.0 Selector spacer for firmware 1.0.3 misalignment

thingiverse

A quick fix to overcome misalignment issues after modifying the MMU2 selector initialization procedure, which Prusa plans to address in a future firmware release. The selector now swings to the left side of the pulley during initial calibration, resulting in a 1mm misalignment between filament feeding holes (see https://github.com/prusa3d/Prusa-Firmware/issues/1422). To resolve this issue, I created a simple spacer that snaps onto the guiding rods. Printed with any material, it provides a solid solution for me.
