CFS Tensioner

This modification improves the retraction of the Creality CFS spool, especially when using lighter spools. It also enhances compatibility with smaller spool brands like Sunlu. You'll need a standard 22x7x8 bearing for the spool, along with a 9.5x20mm spring. Alternatively, you can add weight inside the rollers using ball bearings, coins, or similar objects. The roller without the shaft has a reverse thread for the cap.I hope you find this mod helpful! Your feedback is greatly appreciated.
