Its getting more and more important to do fast prints. So this CFD flow optimized duct helps. As well you get much better bridges if you have a nice cooling flow.
Fits a Anycubic i3 mega. I am working on one for my mk3s.
So i hope many people can print necessary corona stuff quicker.

The wraped horn shape pipe will dispense the air around the nozzle. The flat slots are longer at the entrance of the fan to increase resistance and they are short at the end for lower resistance - so you ensure a even flow around the nozzle.

I did a lot of iterations to get this printed easily. But now you need only support from build plate and the complete inner contour stays free of supports.

Feel free to adapt to any kind of printer - only the connection needs to be changed.

Print instructions

i used PETG because of the higher max temperature.
Prints with supports from buildplate only
enable detect bridges.
