3dprintmi volcano cooling mod

This was modified a bit from the original posted by gyronictonic https://www.thingiverse.com/thing:825277
and also inspiration by Prusa i3 mk3. Credits go to these guys for the original designs, mine was just redesigned a bit. Inverted the fan so it gets cooler air and also fitted the prusa i3 mk3 nozzle for pushing cold air to the part. Inductive sensor was pushed a bit to the side to make more room for air flow and turning the volcano 90 degrees so it's easier to center the nozzle.
