Filament loader for Ender 3 Pro

Doesn't need any other parts, very useful for loading your ender 3 pro with new filament. Very easy to install, just align the flat side on the bottom of the part with the flat side of the bowden extruder that feeds the filament to the hot end. Push down until it is firmly in place. Also a very good indicator to see if the filament is being pushed towards the nozzle.
