CR-7 Filament Guide and Filter

A clam shell design inspired by the Universal Filament Filter. This also acts as a filament guide into the extruder by mounting on the top roller wheel bolt on the Z assembly. Designed specifically for the CR-7 (stock extruder) but could possible to use on other printers as well.

To load the filament filter, cut two squares off of a sponge and place them in the top and bottom of the filament filter canister. Place a few drops of mineral oil and close it up.
