Ender 3 Pro Filament Runout Sensor and Oiler

thingiverse

I changed out my heat break to an all metal one and it was recommended that I use an oiler to "season" the heat break to keep PLA from sticking. So I modified my remix so have an oiler/dust remover right before the extruder. I needed to have enough space between it and the filament runout sensor, so I pushed the sensor back a ways. I now have enough room for the filament to feed past the sensor when it runs out, but not get to the oiler. Now when my filament runs out, it continues forward a little, clears the sensor, then retracts out a ways for easy removal. The all metal heat break works great too BTW.
