Replacement fanduct for Ultimaker stock fan.
Print in the provided orientation, mount with the existing hardware.
I tried one of the fanducts that cool around the nozzle, but found they did not displace enough air. This design has an even more tilted fan placement, which should result in better efficiency.
It may look as if the duct blows on the nozzle, but this is not the case.
