Runout sensor filament guide
thingiverse
This ferrule adapter will help guide your filament into the extruder after the filament sensor. I replaced my PTFE tube with newer tubing that was a little bit smaller outer diameter so may have to adjust size by 5% increments in scale up or down. you want a snug fit or super glue it into ferrule. Also, I did the first one in fast mode i have since done one in detail mode that has less deformities in finish so just FYI
