Modified PRUSA Adapter-Printer-MMU2S Part. This part directs the filament from the PTFE tube to the gears in the extruder. In my opinion, the inlet of the part is too small and steep. This causes the filament to get stuck before it reaches the gears. The likelihood of this behavior increases when the curvature of the filament becomes more pronounced as the roll empties out. To address this issue, I modified the guiding hole into a cone shape and increased the inlet diameter to 3.5 mm.
