Rotating Filament Spool Holder for Ender 3 (Pro)
thingiverse
This is a simple rotating filament holder sleeve that fits over the stock ender 3 (pro) filament holder. The setup uses one bearing at the end of the holder and two to support the sleeve at the mount. The sleeve has flanged ends to stop the filament falling off. There were some other good models out there but I wanted something that was as structurally sound as the original mount so I created this design to fit around it to avoid weakness. The parts are easy to print and the result is a holder that is the same length as the original. Enjoy. Requires 3 x 608zz bearings.
