Sunlu S4 - Revised 3KG spool holder with Bearings

After modifying the S4 with the stock files from Sunlu, i found that the cardboard rolls were biting into the holder. I decided to design up a holder for multiple polymaker spools. This is a drop in replacement from the original Sunlu 3kg modifications files
