Nozzle sculpfun S9

My first remix.
It was a journey and it kept me busy this weekend. The original is from "see_you" but my laser head is different from his, his skirt is 5.5mm and I need 19.2mm.

I also removed 4mm from the hose connection because it suited me better and I also reversed the direction of the blades/holes through which the air from the fan blows. Two stl files are included, one with the original length of the hose connection and the shortened version.
