Lately, I have been trying to find a Satsana Ender 3 fan duct designed for a dual gear direct drive with a BLTouch and a Volcano nozzle, but I found nothing with these specifications, so I remixed the remix design of the Satsana fan duct.

I have also provided a .step file in case you want to modify it according to your needs.

NOZZLE_TO_PROBE_OFFSET { 32.5, 4, 3.3 }

3D PRINTING SETTINGS: 30% infill Material - PETG (You can use PLA also but I would recommend use PETG due to its heat resistant properties)
