Thanks to the idea from carbonbased, I've threaded the filament through these oil-soaked dremel buffing wheels to get the same effect on my Replicator. Working great so far.
Never ever use WD 40 for this!! It's way too agressive. This is what i would use:

What kind of oil are you using?
Check out this mod, it senses the need for filament and helps push it up and also detects if it jams and pauses the printer (with sailfish).
Ha! Truly, that is awesome, but wow that is soo much more complicated than an oil soaked piece of fabric.
