Filament Dust Filter + Lubricant + Stress Relief

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!
