A fan duct for two 4020 radial fans. This is a modified version of this:
Using for a printer below or E3D V6 hotend:
For me it works pretty well :). So I decided to share it also with you guys.
The version V2 has a wider end opening, lets more air to get trough.
The version V3 is even wider that V2 and has a wider duct, it has less space for the E3D mounting bracket, so you might need to check if it fits.
I have also included the source file in case someone would like to further modify it.
