Fan duct and grill adapter 3" OD

This 3D model of the Creality fan duct fits the Creality Laser Enclosure.

3" outer diameter, screw holes match the enclosure's original fitting. The protection grill is meant to avoid large debris going into the duct/fan.

In the pictures,  you can compare with the original (in black) and see fit in the Creality enclosure. The original has a tapered profile where the tip of the hose attachment is slightly less than 3". My model is not tapered and will be a snugger fit.

Printed it in Creality Hyper PLA, no support or special preparation is required.
