Prusa i3 Mk2 Idler Redesign
thingiverse
The axis of the original idler, which is black, is positioned about 1 millimeter higher than that of the extruder. This discrepancy can cause feeding issues with very pliable materials. I replicated the design and adjusted the ball bearing's position by lowering it 1 millimeter, resulting in a precise alignment with the extruder axis, which is red.
