Smart Filament Sensor Holder Ender3

This is an holder for the smart filament sensor from BigTreeTech.
It is for Ender 3 V2 (Perhaps also for other Ender 3).
I have used a littel bit longer screws.
Its designed with tinkercad.

Now i have tested it. I think it is better if the sensor is before the extruder motor.
Because if the sensor is behind the extruder motor perhaps it is to late and some lines are not printed. If it is before you have a few centimeters of filament to extrude until the sensor detects it. So i have moved the sensor before the extruder motor.
