Modified Spool/Roller Holder

thingiverse

I loved the original design here --> www.thingiverse.com/thing:4192822 You will also need the rest of the files from there to complete this item successfully. My issue was specifically with the sleeve and the spool of filament constantly working their way off the roller holder. This original roller system almost worked too well, causing several rolls about 1/2 off, including the roller sleeve, and on one longer unattended print, the filament spool actually worked its way completely off and fell to the floor. The problem lies in the flange on the end not being high enough to prevent them from working their way off after several rotations, possibly due to a slightly off-level bench towards the back - I don't think so! I could have easily bent the whole spool holder up so gravity would hold the spools and roller in place, but that didn't seem right. I took the original holder and added a larger flange to the end, which then created an issue of getting the sleeve on properly. So I reduced the size of the flange on the threaded end, allowing you to slide the sleeve on before screwing the whole setup onto your printer. Once the threaded end is screwed onto whatever printer you have, there's no way the roller or spool can get off on that side - the added flange on the opposite side keeps it all securely in place.
