Filter for CFS

I have slightly improved my modeling skills, and finally got around to upgrading my CFS filter while preserving all the original advantages:• Play between parts has been eliminated• The design now has smoother edges• The filter is slightly smaller• The sponge holder has been redesigned• Sponge hooks have been added, so the sponge is held even more securely• The filter can remain installed while feeding new filament• Most importantly, it still locks onto the fitting and prevents it from popping outPrinting recommendations:• I now recommend printing in PLA• I recommend trying vertical printing• Supports are required• Remove supports carefully• All other settings can remain defaultUse a 2 × 1.5 sponge piece and magnets of your choice.Please note!Each filter has its own design.
