Update
I thought I could increase the airflow a bit more, allowing it to focus even better by cutting out a bit more material. There are two additional versions. One with a crescent cutout and the other with more of a 'ramp'. Every little bit helps.
This is an iteration of my previous design (https://www.thingiverse.com/thing:5386502). I didn't want it to get lost as just another part, thus it has it's own page.
This duct is virtually identical to the other fan duct with one very important exception. Airflow is now more focused on the nozzle due to a reduced opening near the hot end. It still prints well (even better) without supports and there are two models to accommodate those without extra long M3 screws laying around.
*This was designed with the Microswiss all-metal hotend in mind. It may not properly fit other hotends.
