If, like me, you prefer to mount your spools on a surface above the frame of the Ender 3V3 KE to reduce vibration and make it easier to load filaments for multi-colour prints, this guide keeps the filament running smoothly regardless of where the spool is situated around the printer.

It slots easily and securely into the two screw holes that are no longer being used for the original spool holder.

3D PRINTING SETTINGS: Any filament at whatever settings your printer is happy with.
