Creality Pro 20 Spool Holder Bearing upgrade

thingiverse

I engineered an attachment utilizing miniature bearings (FBJ 685ZZ (4x)) to minimize drag and enhance the movement of the filament spool during printing. The design clamps securely over the standard spool roller (Creality Cr20 Pro) and is firmly screwed in place by connecting the top and bottom components using (3x12 mm (8x) and 5x35 mm (2x)) threaded fasteners. This setup ensures that none of the original parts need to be removed or replaced. The bearings glide effortlessly over the 5x 35 mm bolts, which are held in position by a small spacer.
