Just a modification with larger ducts. I am doing a curtain fan adapter for the Creality CR6 and its height is 9.5mm, so I needed to compensate the duct lenght for reaching better to the parts. This can be used like the previous models, not only in the CR6.
Print with supports!
I recommend you to print them from the flat side (where the fans are mounted).
