New Dual Side Duct Design for Ender 3 V3 SE part cooling.

The objective of this design is to get better cooling out of the default cooling fan of Ender 3 V3 SE without additional fans or modifications to the electric circuit. This design is lightweight, since it does not contain the cover for the extruder.

- This dual side cooling provides cooling from 2 opposite direction which allows better overhang and angled printing.

- It has more air flow than my previous design.

- Maximum airflow is limited by the fan.

- In some cases, this design might work well, in some cases, it might not. You can try and give feedback.

This is still under development. If you would like to try it, use it at your own risk. Read the installation instructions carefully.

Installation instructions:

⚠️ Before printing, orient the parts as shown in the slicer image above.

⚠️ Do not use PLA for the duct. Else it will deform/melt due to convection heat transfer from the nozzle body.
⚠️ Turn off the power and then carefully assemble the body

⚠️ To prevent air leak, it is recommended to use any some electric tape or any other kind of tape will do the work (as shown in the image).

If you want to help optimizing the design, please feel free to share your design or feedback.
