Custom Fan Duct Mod

thingiverse

I've been having issues getting the original cooling fan to fit my Ender 3 Pro. However, after making a minor adjustment, it was perfect for me. Perhaps this tweak will work just as well for you guys too. I printed at a height of .12 layers with 30% infill - I actually had seven walls in place, so I printed without infill at the end to avoid any issues. Support structures were also added for good measure. Make sure not to over-tighten the screws; you'll know it's at the right angle when you see it.
