Thank to share your nice job.
I have appreciated your step part

Nice work ! It printed very nice even without a cooling fan and it didn't need supports. :)
This is one of the nicest designs I have seen so far.


Hi what is difference between e3dv6dualductbig.stl and e3dv6dualfanblower.stl ? In those files how big are fans?

I have 40 heatsink fan and look for proper model to print. What is more, I have heater cabling on other side so I can't print one with circle around nozzle.

you say in yout description 40x40 mm but its only 30 after printing it. Is there one that is 40?

which one is the best?

which one is the best?

wish there was one like this for the volcano hotend!!!

Hi again!
This is the best fanduct I've tried so far.
I'd be great if you can edit no ring version for 25mm center fan. I've found a nice quiet fan that I'd love to use.

40mm version can be used with 20mm thick fans or only 10mm?

With any. Depends on how much shaking or vibarating you want.

Works perfectly, thanks for this!

hello friend, great job. I wanted to ask if it was possible to modify the support to put this support on a fan 40 and not 30mm. All fans from 30mm I bought are too noisy, I would like to print a support for 40mm fan and put on your project. thank you

Hi. Thanks. Yep I think it's no problem to make it this way. The qustion is what clap are you using for the heatsink, original 30 with adapter or 40? I will upload the STP if someone wants to change it.

I need to install a 40x40x20 without adapter.

Added. Trying it now by myself. :)
