Filament Dust Filter + Lubricant + Stress Relief

thingiverse

This compact, easy-to-print companion efficiently cleans, lubricates, and feeds the filament into the feeder, minimizing bending stress. It does all this without requiring removal of the filament from the printer. I engineered it to be modular, meaning you can use one or multiple central components as needed. Here's how to utilize it: 1 - Fill the central section with cotton. 2 - Attach the extremities, ensuring the cuts are aligned. 3 - Insert the filament; importantly, no 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 - Rotate the parts so that the cuts are not aligned. 6 - Enjoy!
