The modded buffer wheel is 1 mm thinner, and the bearing goes in too deep, creating a gap between the buffer wheel and the arm. I added two spacers to fix the gaps, but since the modded buffer wheel is 1 mm thinner, it allowed me to create a bigger spacer that helps keep the filament from wandering into the arm hexagon hole (yes, it happened to me) and, in general, helps keep the filament from going to the neighboring buffer.
