Filament sensor mount Flsun

Modified version having a much smaller size but building on the same idea of having the sensor right above the extruder entrance place.
Just buy a 10 dollar sensor and connect it to the e wm_det port on the flsun board. I needed to buy a 3-pin jst sm extension cable because the cable was too short.
Also a zip tie is needed for connecting the sensor. And last but not least either use klipper (Google cobrapi klipper qq-s)
or foxies marlin version. In the install you will find how to enable the sensor.
