K8400 VERTEX Filament Dust Filter

I designed this filter after being unhappy with couple of other filters posted here.
The bottom part mounts to the side of the printer right under extruder. Top part can be put in place and removed with no screws. There is no need to unload filament when installing this filter.

Cut out 2 pieces of foam and insert them into each of 2 pieces. Put several drops of mineral oil on the foam, pass the filament through and push top piece into the bottom.
