If anyone wants to build upon this, I would recommend to start with the Gen 2 version instead.
This is a part cooling fan mount/duct, that I designed for lipki's direct drive extruder design: https://www.thingiverse.com/thing:2665491
This was my first attempt to create a fan duct, so it certainly has room for improvements. I couldn't find a position for a 5015 blower fan with which I was happy, so I used a 4020 radial fan for now.
If anyone wants to improve upon my design, I included my Fusion 360 project.
