Filament Spool Roller - Snap Fit 6x19x6mm Bearings 626zz

thingiverse

A roller set I had was too wide for the bottom of my rubbermaid dry box containers. I liked rc101's snap fit design but it was for big bearings that I don't have handy. I've not had much luck with remix or edit of .stl files, so I drew up a bit different but similar snap together concept for smaller 626zz bearings (19mm OD 6mm ID and 6mm wide). A single .stl file has a side and foot parts so print 4 to make a roller set. Each side has a single post for the bearing axis that lightly snaps into the opposing side pocket/hole. Then the feet press on with a tight fit to complete a solid filament roller base structure. Update: SpoolRoller V3 file has the curved part of the side rail lowered 3mm to help reduce drag that a new spool might present. This is the file I recommend using. My dry box parts started with this filament spool roller for a Rubbermaid 21Qt canister. I used PTFE Teflon tubing 3/16" ID x 1/4" OD for my 3mm filament and drilled out UKWEBB's https://www.thingiverse.com/thing:2170536 Grommet for the feed nozzle. A rubber cap on the PTFE stub seals the container for storage. I added a spacer cad file to keep the rollers appropriately spaced in the bottom of the dry box container.
