thingiverse
Yet another filament guide for your Ender 3 V2. Not much filament and printing time required, a single screw M4 x 15 (in ender 3 V2 kit as spare) and a ball bearing 689RS (9 x 17 x 5). Supports required for the arm, check out in the pictures how to place items for printing. the pulley prints in two parts which then click together, sandwiching the bearing in place. If needed, add some glue to make the pulley assembly permanent. Update 21/02/21 : updated arm so that filament comes into extruder perfectly horizontal.
