The file '120 Mm Fan To 4″ Dryer Vent 3D Printer Model' is (stl) file type, size is 164.0KB.
I needed a exhaust for my laser engraver. I used a 120 mm pc fan, a PWM controller, a 12v power supply, and 4" dryer vent. I'll include pics of the entire project but here is the STLs.
I added a chamfer to the fan adapter like the outlet had.
Enjoy.
