Geeetech Prusa i3 pro extruder fan duct mkII

I merged my previous Geeetech prusa i3 pro extruder fan redirector with a 40mm fan duct.

You can try printing as a single piece using supports or you can print the mount and the duct part separately.

I printed them separately and then used the extruder to join the 2 pieces together, manually.
I also tapped the holes for the M4 x 20mm screws that mount the 40mm fan to the duct.
