Ender 3 + Direct Drive "Bullseye" Fan Duct

I wanted to use the excellent bullseye fan duct on my Ender 3 but I've changed mine to direct drive with the genuine Creality kit. Anyone who's tried this will find the feed motor is in the way for the cooling fan.

I have remixed the bullseye duct to angle the fan 15degrees - it's a tight fit but works perfectly.

I take no credit for the duct and I can't guarantee the airflow is as good although I have smoothed out the path of the air from the fan so it should be just as good as the original.

This design uses the stock part cooling fan and the Bullseye mount that you can find here:

This is my first ever 3D model and I'm really happy with it!

You might have to lightly sand the gaps for the fan to slot into as it's quite tight.
