Hi, the design looks really good, but I have a problem. I have already printed amost all parts.... All of tehm fits perfect, teh thing rollls with no problems. But I wanted to use a spool less filament, a laywood roll. There is a picture here showing a laywood roll. But, has anybody actually tested? because I tried and the filament just gets out of the arms, and basically after some filament being used, the roll is a mess around the center and the holder just dont roll anymore. The filament "escapes" to the inside, not to the outside of the spool holder. Any solutions?
