k8200 FanDuct
This thing was made with Tinkercad. Edit it online https://tinkercad.com/things/4fFz9lAY2qy
I made this because the ones I found ether did not work with the standard fan or the outlet was too small to allow good air flow. This directs the air without reducing flow. I put heat reflective tape that is cheap and from local hardware store.
