print all in one part filament cleaner

thingiverse

Here is a filament cleaning box that prints easy and fast, all in one part, open and flat on bed. It requires no supports. This handy cleaner opens to fit over existing filament already fed through your machine. Simply print it flat on its back with two open compartments facing upward. Add a common kitchen sponge cut to size in each side, a few drops of Canola oil to the sponges, and you're ready to go! Clamp this box to your filament just before the extruder to keep your filament clean and prevent contaminants from clogging up your nozzle. If you print or use this design, please share your photos with me. I've updated the model for printers that were having issues initially by reducing the tolerance. Additionally, I've made further updates to the files. The spring catch is now more flexible. You can print the filament cleaning box without supports using filamentcleanpsd.stl or with supports using filamentcleanpsdsupports.stl, which I've incorporated into the model for your convenience.
