HE3D K200 Extruder bushing / filament guide

thingiverse

I have an HE3D K200 and I'm fed up with jamming the Bowden tube into the extruder gear every time I pull on the filament, forcing myself through Mission Impossible 1, 2, and 3 to thread the filament past the drive gear, through the threaded extruder lever and into the new PC4-M6 fitting that prevents the Bowden tube from getting pulled into the drive gear. So this external M6 thread screws onto the extruder lever, the PC4-M6 fitting fits on top, and there's a nice funnel over the drive gear to help guide the filament up into the Bowden tube. I ended up having to cut the funnel again with a scalpel to get a good fit, but if the part doesn't work out, maybe the idea will save me in the long run.
