Filament Spool Holder Roller for Ender 3S1

thingiverse

This design for an Ender 3S1 places the bearings in the Creality spool holder. Two bearings fit in a bearing ring with a 35mm 8mm threaded screwed into the roller. A washer fits between the roller and bearing for clearance. To prevent the bearings being displaced a retaining washer and a locking ring fits in from the opposite side. To ensure the clearances are correct both the clearance washer and retaining washers can be adjusted in the slicer Z axis for fine tuning. Hardware used is 2 x 608 bearings 22 x 8 x 7mm and 35 X 8mm threaded screw. Any concerns of rolling action unlocking the rings then they can be mirrored in the slicer to make them an anti clockwise installation. I have added a remix that locks the spool to the roller as an alternative.
