Fully printed bearing spool holder

thingiverse

This spool holder was designed specifically for a 2kg spool measuring 300x80mm.\r\nMy previous spool holder lacked the smoothness needed to handle such weight.\r\n\r\nAll components were crafted with a 0.2mm layer height in mind, as well as compatibility with a 0.4mm nozzle.\r\nThe bearing consists of multiple bodies combined into one .stl file, containing the three parts that form the housing for the rollers.\r\nYou will need to print 23 individual rollers or a total of 46 pieces to complete the bearing assembly.\r\n\r\nThis design demands precise printing from your machine, with no clearance between stationary components and rollers having only 0.05mm clearance.\r\nThe two parts of the bearing are held together by a single continuous extrusion, requiring no support during printing.\r\n\r\nIf fitting issues arise, consider using your slicer's scaling options to add spacing (shrink the part), or manually sand down the components until they fit snugly.\r\n\r\nTo accommodate spools of varying dimensions, use your slicer's scaling feature to adjust the width as needed; however, altering the frame height is not feasible due to the bearing's size constraints.\r\n\r\nThe optional collar piece is designed for users with particularly large central holes in their spool.\r\n\r\nThis design functions well and should be adaptable for multi-spool use with a longer beam, although it can be somewhat delicate when switching filaments. Gluing the components together resolves this issue, but a future single-sided design is planned to simplify filament changes.
