3D model description

A circular part cooling duct for 30mm fans. Tested while printing and with smoke. Not the biggest cooling effect but very evenly and not effecting the nozzle too much.

  • Updated with a 40mm fan version and optimized airflow.
  • Updated with a 40mm fan B variant that has an additional duct blowing directly under the nozzle.
  • Updated with the final 40mm variant with larger opening on the bottom and an additional shroud that uses the hotend fan to direct more air to the print. This combination produced best results.
  • Added STEP and IGES files for modification :)

I did a simulation to test the airflow and it matches the results I observed when testing with smoke. You can watch it here https://youtu.be/EhtRSBZZycE
