I needed a simple nozzle for my 5015 blower so I designed a really simple one. It is mounted with a single screw.
I´ve prepared four different versions:
Wide: Outlet size is about the same as the inlet size for maximum air flow over a wide area
Narrow: Smallest ;)
Update 24 Sept 2017
Narrow-long: This version is 15mm longer than the original narrow version
Best printed without supports and the nozzle tip pointing down.
FreeCAD source files included.
1 x printed blower nozzle of your choice
1 x 12V 5015 Blower fan e. g. from Aliexpress
1 x M3 x 20mm bolt e. g. from Aliexpress
1 x M3 nut e. g. from Aliexpress
Nozzle 0.3mm, Layers 0.25mm
