This air duct is designed for a radial fan with the dimensions of 40 x 20 mm at the air outlet.
The air duct is printed with the following settings:

- filament of wood with 3 mm diameter

- nozzle with 0,4 mm diameter

- layer thickness of 0,2 mm

- 100% filling

You have only to drill two holes in the bottom plate of the 3D-printer to fix the fan with the two screws.
To reduce the noise of the fan, I placed foam material between the fan and the printer housing and between the air duct and the fan.

Materials and methods

2 x screw M4x40
2 x nut M4
2 x washer for M4
some foam material with ca. 5 mm thickness
