JeSc Tevo Tarantula Layer Fan with 18mm sensor

Made both fan ducts using http://www.thingiverse.com/thing:1591912 by sobezuki, published May 27, 2016

And the 30-40 version I also used http://www.thingiverse.com/thing:1759396 by Galane, published Sep 8, 2016

I added an 18mm inductive sensor holder as an upgrade

Print both in ABS, because it is very close to the hot end and PLA will melt!

OFFSET SENSOR:
Y offset = 0
X offset = 40
Z offset = up to you ;)

Adjust Marlin firmware configuration.h (approx. line 604-605)
define X_P
