Air Assist AUFERO LASER (1-2) LU2-4 SF- 3 blowing nozzle

Remixed the Frederic one and changed orientation of all nozzle, to avoid the air flow to leave an uncovered axis. This air assist blows to cover completely the cut on all movements of laser. 

Holes on nozzle are 1.3mm diameter: if printed with FDM is necessary to enlarge hole drillling through with a 1.5mm drill bit, to ensure right air flow.

In my tests the cut is completely clean. Used with a 35 l/min air pump.
