Universal Spool Holder (2020 AND 1515 frame mount)

thingiverse

This spool holder attaches to a 2020/1515 aluminum extrusion frame, and it can hold all 1kg (2.2lb) spools of filament, including the 1lb Taulman filament spools. Every time my printer retracts I see the spool move, showing very free movement and no tangles with the one I have been using. The BOM and Exploded diagram are attached to help you assemble the holder, or you can go to http://www.instructables.com/id/Frame-Mount-20201515-Universial-Spool-Holder for build instructions. If you need a shopping list, the attached CSV file has everything you will need. Build video and threaded part by Gregory Nutt - https://youtu.be/JKv47Z0bjf0. Thank Gregory for his hard work fixing this design and improving it! Updated April 30th 2016: added link to build instructions at http://www.instructables.com/id/Frame-Mount-20201515-Universial-Spool-Holder. Updated April 20th 2016: found issues with the M8 screw in the BOM, and fixed the problem by replacing it with a fully threaded screw. The old part number was incorrect. Revised on April 15th 2016: complete redesign to improve tolerance stack up issues and the screw depth for the 2020/1515 frame mount. Added new center piece and outside piece for holding the 8mm bolt and nut respectively. Revised on April 8th 2016: added a frame mount for 80/20's 1515 extrusions. Revised on February 14th 2016: uploaded new stl files and step files, changed part orientation so no longer need to be rotated before slicing.
