Tevo Black Widow auto-level sensor mount

mount for adding an inductive or capacitance sensor to the Tevo Black Widow. This mount places the sensor approximately 30mm to the right and 16mm in front of the nozzle.

*added a v2 mount that works with my extruder spacer http://www.thingiverse.com/thing:2188117

I used a LJC18A3-H-Z/BX sensor, and connected as follows:

BLUE (-) to PSU ground
BROWN (+) to PSU +24v
BLACK (sensor output) to a 1N4001* diode (anode) then diode (cathode) to Z MIN input on controller (black wire).

I just cut the wires to the original end stop and soldered the sensor to the black wire on the connector.

*if you're worried about the voltage from the sensor causing damage to the controller, you can use a 5v zener diode instead.

**NOTE** If you're using a glass sheet on top of the heated metal bed, like I do, this sensor DOES NOT detect the glass, but the metal bed under the glass. You can get it to detect the glass if you turn the sensitivity up high enough, but even then, it will still de
