E3D v6 Bowden extruder holder mount Prusa i3 with clamp mount for induction sensors 12mm and 18mm

This THING is a remix of another design of mine: http://www.thingiverse.com/thing:2111212

I've included a inductive sensor mount, since I use one for bed autoleveling. There are 2 versions of mount: One for 12mm inductive sensors and another for 18mm inductive sensors.

Both designs are Y axis aligned.

The X axis offset for the 12mm version is 31mm
The X axis offset for the 18mm version is 34mm

With those informations it will be easier to set firmware calibration for bed autoleveling
