Inductive sensor support Anycubic kossel linear plus M8

You can use this thing to apply an inductive sensor (M8) to your delta kossel linear.
This thing can be connected using the same holes already used to apply the main cooling fan.

I adopted the firmware configuration as follow:

#define Z_MIN_ENDSTOP_INVERTING true // Set false for probe switch, true for inductive sensor
#define NOZZLE_TO_PROBE_OFFSET { -41, -11, -1 }
#define MIN_PROBE_EDGE 50 (Ultraboard 240mm diameter)
#define Z_PROBE_LOW_POINT -20 // Farthest distance below the trigger-point to go before stopping
