Creality CFS Filament Filter for K2 Plus and Hi Combo

Cleans your filament before it enters the CFS. 

In my pictures I've printed it using a 0.2mm nozzle on my K1C for a smoother transition but it should work with 0.4mm nozzles as well (I did not test this though).

No supports required. Optionally allows for the Capricorn XS blue tubing (1.9mm ID), but you do not need to use this. I found some of my spools have an insanely tight bend at the last bit of filament that is causing issues so a narrower tube helps to straighten it out before entering the CFS.

You need 4 filters and 4 PC4-M10 connectors:

You can cut your own sponge as well but it should be about 25-32mm long. If it is too short the funneling into the sponge won't work as effectively and your inserted filament might push down onto the sponge inside.
