Summary

Hi all.
That's my version of fanduct for 30x30mm fan to use with boards that have five inline stepper drivers installed right next to each other (like on SKR 1.3 board).
Fanduct have small latches on both sides, so it will "catch" driver PCB between them. Some assymetry is added to prevent latches damage trimpot on PCB. Be carefull removing support and try not to snap latches :)
I recommend to print it with ABS filament or other one with good thermal characteristics.
You can use 2,5mm self-tapping screw to mount fan.
