AC-27 reducer nozzle

shrunken nozzle for the AC-27 blower from A little more than 21mm to 11mm and 16mm. This will work with many other brands that look similar. I have tried the 11mm version and it feels too small for the blower if you are running it at full speed. I haven't tried the 16mm version yet, but I think that it shouldn't cause as much back pressure causing air to escape from the vents around the blower.

Added a Fusion 360 file.
