Filament Sleeve

thingiverse

I printed the spool holder and nut, which is a fantastic part but comes up a bit short when it comes to my filament spools in terms of size. Even after tightening the nut as much as possible, the spool can still slide downward during printing and start to unwind, causing problems, especially with new spools that have some real weight to them. I recently came up with a sleeve for it using TinkerCAD and gave it a try. It fit perfectly and really helped tighten the filament spool on the roll in place. So far, no unwinding has occurred with it.
