Kingroon KP3S PRO V2 Dual Duct

A balanced airflow dual duct. Print the body and ducts as per the pictures in the orientation shown. I used super glue to bond the ducts to the body and I printed in ordinary PLA. I used an infill of 15% (cross hatch pattern) 3 walls, 4 layers top and 3 bottom. Using a brim to ensure the ducts and body stay on the print bed is a good idea! No supports are needed. If you use Orcaslicer I also used thick bridges and detect thin walls.

Added:

A version to fit a 5015 fan.

Changes: 

1st June 24 

Tweaked Body_21 to have easier internal geometry as noticed some slicers struggled with the internal bridges. (Orcaslicer v2.0.0 was fine) still to do:  update 5015 body

Note: 

There's two variations of each body. One uses 3mm brass inserts. The other doesn't.

Other Info: 

On the ducts fitted to my machines, I trimmed (cut) the left hand mounting screw down so it fits flush with the inside of the body when screwed in. As supplied it's a little on the long side and sits directly in the airflow. Which isn't the best!

Lastly:

The pictures show the orientation of each part on the print bed.  For the very best results I'd print the body by itself and then the two ducts by themselves as individual objects rather than altogether in layer mode.

Happy printing! :-)
