Thankyou for your efforts making a good upgrade and include both fan types and all kind of senseor holds! I was thinking over what cooler upgrade to chose for my Ender3 and yours seems to be the best easy to handle solution. I have 2 questions though:

  1. Why did you make the cross ribs, vertical and horizontal inside the main (base) body airflow duct? Do they actually help to distribute air flow?
  2. I couldn't find 4010 pipes in your source file. Can you please include it?
