CR-7 Filament Guide and Filter

thingiverse

A clam shell design inspired by the Universal Filament Filter is used here, which serves as a filament guide into the extruder when mounted on the top roller wheel bolt of the Z assembly. This design was created specifically for the CR-7 stock extruder but can also be utilized with other printers. To load the filament filter, two squares are cut from a sponge and placed in the top and bottom of the filament filter canister. A few drops of mineral oil are added before closing it up.
