This is a filament guiding bracket for Ender 3, if you wish to reposition thefilament spool from the top of the printer. It guides the filament from the side or the bottom of the printer with a roller bearing. This helped me a lot in reducing the vibrations and swinging during the printing. It can be mounted on the top of the extruder with the factory bolts.
