Dropping Filament Runout (Sunlu S8/Creality CR-10)

Falling arm for the filament runout sensor on the Sunlu S8 that is designed to align with a BMG extruder. When filament runs out the sensor will drop out of the filament path to allow the unload script to continue without trying to push filament back through the sensor.

Designed for use with Marlin 2.0 advanced pause feature with the FILAMENT_RUNOUT_DISTANCE_MM set to 20.

May also fit the Creality CR10 but untested.

2x M3x16 (or glue) to mount the sensor to the arm

1x M3x6+ (or glue) to mount the bracket to the extruder plate
