Sunhokey Prusa I3 Modification for Smooth Filament Flow

thingiverse

So I experienced jumping extruder motor and clogged nozzle, and upon investigating, I discovered teeth marks left by the extruder gear on the filament. I suspected these markings were causing the issue, so I tried adjusting the tension on the extruder clamp to avoid future marking, but the problem persisted despite my adjustments. Now that I couldn't eliminate the teeth marks entirely, I focused my attention on the passage where the filament moves through and discovered edges that could catch or rub against the existing markings, hindering motor progression. To resolve this issue, I smoothed these rough edges by creating a chamfer on them. I also created chamfers on both the PTFE tube and the interior nozzle to prevent further snagging of the filament. Problem solved!
