Ender 3 Pro Spool Holder Upgrade

thingiverse

Works great for reducing load on the extruder motor because the bearings let the reel spin freely compared to stock. Requires three standard longboard bearings (22mm OD, 8mm ID, 7mm thickness). Prints in three separate parts that can be assembled together. Pictures show one previous iteration where I had to cut apart the plastic to make it fit on the bracket side. This issue has been fixed and the part now requires only minimal post-processing, such as brushing off strings and removing supports. PLA might work, but PETG prints are probably better because they are super strong!
