Filament filter holders

Sometimes the dust (including the parts of cardboard from spools) comes with filament to the nozzle. This can spoil your print or even clogs the nozzle. To prevent this, you may use the filament filter. I'm using Creality filament filters.This models accepts standard filament filters. You can install it inside and change when it wear out.To install the holder into CFS, remove existed guide cap (by pressing on the ring), install the cap into the holder, than install the filter.Cut PTFE tube in a half and install holder-cap-filter back into CFS.Holder for PTFE gap using two PC4-M10 fittings.Neccessary to smooth internal parts of PTFE ends with a drill bit or something sharp.V2, upgraded version.For removing the filter from the holder use flat screwdriver.On v2 everything easy, by hand.Printed with PLA.
