This is a simple spool support and filament guide for Ender3 v3 ke. The main objective is to reduce the vibration you get from having the heavy spool over the printer.
You will need an M3 screw and nut to fix the filament sensor. An alternative is to print a small square with a 2,4mm hole and glue it to the filament guide.
The author marked this model as their own original creation.
