Filament Dust Filter + Lubricant + Stress Relief

thingiverse

This small easy-to-print little buddy cleans, lubricates and drives the filament into the feeder reducing bending stress. All this without removing the filament from the printer. I designed it so to be modular, this means that you can use more than one (or none) central pieces, according to your needs. How to use it: 1 - Fill the central part with cotton; 2 - Add the extremities aligning the cuts; 3 - Insert the filament; N.B: you don't need to remove the filament from the printer! 4 - Twist the caps counterclockwise a couple of times to wrap the cotton around the filament; 5 - Turn the parts so that the cuts are NOT aligned; 6 - Have fun!
