This is a quick print that both cleans the filament while printing and holds it securely in place when the filament is not in use.
This was printed in two pieces that have a large cavity on the inside, where you place the cleaning media, which in my case was a cloth that I cut to width and rolled tightly around the filament. I then pushed the cloth into the cavity, applied superglue, and held the two pieces firmly together while the glue set.
If it does not hold your filament firmly to the spool, please use some tape or cloth to close the gap
Measure the thickness of your filament spool's walls and pick the files that will fit the best form their names.
Man, my English is broken today... Sorry about that... I gotta sleep...
doesn't matter, but I used 0.2mm
sorry for the poor print quality in the pictures, my main printer was occupied so I had to use my old MP select mini with z banding
