Filament Sensor Holder for Petsfang Direct Drive

thingiverse

This is made for Petsfang Bondtech BMG, so it can sit on top of the Bondtech BMG, but it will also work for direct drive variants of petsfang if the path is straight with hotend, just use PTFE tube in between. Beware, this will never work for bowden, since motor is placed below the sensor input position and sensor is after the motor! That case you must look to place sensor before the extruder.
