I designed an attachment that uses small bearings (FBJ 685ZZ (4x)) to reduce drag and improve the motion of the filament spool while printing. The design clamps over the standard spool roller (Creality Cr20 Pro) and is screwed in place ( 3x12 mm (8x) and 5x35 mm (2x)) by connecting the top and bottom pieces. As a result you do not have to remove or replace any of the original parts. The bearings slide over the 5x 35 mm bolts and a positioned via a small spacer
