Ender 3 Pro Spool Holder Upgrade

thingiverse

Works great for reducing load on the extruder motor, as the bearings allow the reel to spin freely compared to stock. Does require 3 standard longboard bearings (22mm OD, 8mm ID, 7mm thickness). Prints in 3 separate parts that can be assembled. Pictures are from one iteration back, where I had to cut apart the plastic to make it fit on the bracket side. This has been fixed, and the part should require no postprocessing aside from brushing off strings and removing supports. PLA would probably work, but I just got in my PETG and wanted to use it. Now I know its super strong too!
