Filament Sensor (Updated)

I remixed this from Mine2209:

I modified it for my Tronxy printer filament connection with some small changes and shifted the senor location slightly as well as extended the top to allow a more snug fit of the tubing.

I put all the wiring inside using a 3mm LED blue LED rated for 3.3 volts. With the key pointed upward, like in my picture the soildering points that match the micro switch connection labels is below:

C (Senesor signal)
NO (Ground)
NC (+ 3.3 Volts)

I used a shrink wrap on the leads of the LED to prevent it from shorting or touching the other pins, the wires were about 12mm and 15mm. The Tubing that comes in from the top to the extruder is cut in a slight angle to provide a bit of a filament guide as well.

I placed a dab of crazy glue below the connector to keep it in place but it's not 100% needed, As long as you don't mind a slight height difference the original cover works on it still.
