Filament Oiler
thingiverse
This is a filament oiler. I have seen some online stuff where you can oil your filaments slightly to prevent print head blockages. You file the cylinder with stuffing material for dolls and soft toys, you then feed the filament through the ring cover and outer cylinder. Slide the inner cylinder to cover the stuffing and then slide the ring cover over the frame of the cylinder. at the top of the cylinder is an oiling hole where you can squeeze 2 or 3 drops of oil into the cylinder. The cylinder rests on top of the extruder if you have a direct drive system. For bowden's on the outer side of the feeder motor.
