Fillament spool with adjustable diameter
Description
I happen to have a bunch of 100m fillament samples of different types without spool, exisiting spool designs had unfitting inner diameter, and i'm not even sure, that all my samples have same coil size, and revinding of 100m of fillament woould be a great pain (i tried it once manually and it took several hours). So, that lead me to creating my own design, of spool that could be reused with fillament coils of different sizes. The spool uses snap fit joints, so is easy to assemble, and don't require extra tools. To change size you need just rotate adjuster disk against all other components. Maximum inner diameter: 150mm Minimum inner diameter: 86mm Inner height: 43mm I designed it to be printable with pla, with more flexible materials like abs or pteg snap fit joints would work even better. Some parts of adjuster and top cup need supports, vertical limiters should be printed with mounts touching print bed, to assure maximum strenght.
