Frankenstein's cooler for 40 mm fan with 18 mm bed sensor support

Added the sensor mount to the Frankenstein's cooler with 40 mm fan. Pushed a little bit outer the sensor so that it does not collide with the new 40 mm fan perimeter.
Hope is enough to use both systems in Frankenstein :)
As soon my parts arrive will print it and check if it works.

Cheers all.
