This uses Noctua's fan duct geometry https://www.printables.com/model/887071-nv-aa1-12-airflow-amplifier which is attached to frame and pointed at bed.
Duct is cut so that full bed travel is not limited. The lower the fan is the better - I'm not sure how much clearance in Z axis there is. It should be 10 mm but….
Best bed position is around Z= 250 - 300 mm
Tightening the M6 bolt to 3030 extrusion is a bit of a pain but it's possible. Worst case tighten just the front bolt - it should be fine.
Can be printed without supports if you'll survive the one small area with a few unattractive layers before the print catches back on.
