Download Free 3D Model FanDuct_2in1_40mm_E3Dv6 3D Print Model

Summary
Note: Design still underwork for further optimization.
if you try it please leave a comment with any suggestions or improvements.
This fan duct is for E3Dv6 hot end and 40mm cooling fan. Most of the air flow will go to the hot end, while the rest will be channeled to the nozzle for the print coolling.
Use a fan with enough airflow as it will work as two fans in this case.
if you have any issue to make the duct fit your hot end try heating the duct with hot air gun or even a lighter and tighten the hot end holder a little. I made the radius 22.6 which should be a tight fit.
Note: i didn’t have a chance to test the performance yet, use this design on your own risk !

How I Designed This
Design
I made the design in onshapehttps://cad.onshape.com/documents/3356695e1da2314ad442feda/w/59279bd06eb41761369fb7fe/e/b5880c6902c8ea97b1940c04
It is public so if you would like to make your own changes you are welcome.
I put in mind:
1) Air flow to hot end cooling and print cooling
2) Fit on the hot end ( shouldn’t fall down while printing ! )
3) Distance from the nozzle and the heating block
4) minimum size that doesn’t interfer with other parts in the printer.
This is the 4th print, in every print i test all of my criterias and optimize further.
