Exhaust for roof window

I designed this, in order to extract fumes from soldering and 3D printing directly out of the closest window. For this I use the AC Infinity Cloudline A4 duct fan.

The model consists of three parts that can simply be stuck together. The air inside the model is guided through four flow-optimized channels. A 100mm (4inch) hose can be connected at the front.

Following use cases are possible:

• Fume extractor
• Air Intake
• AC exhaust. Note: The opened gaps on the side of the window have to be sealed with an insulating material.

The model was designed for following type of window: Roto WDC RotoComfort i8

I also uploaded the .stp-files so you can adjust it to other window designs.
