A simple blower nozzle designed to fit the 16x20mm outlet of a 5015 blower common on 3D printers. My blower was measured to have a maximum static pressure of 18 mmH20 and is specified with a max CFM of at least 3. This nozzle is designed to give 15m/s outlet 
velocity at 1.5 CFM  with 14 mmH20 static pressure, which should approximately match the load curve of my blower.
