This is a remix of mediaman's Hero Me Gen2 fanduct for dual 5015 action. Since I use buck converters on my Ender 3 to get 12V out of the original 24V I needed a place to put them on the carriage. So I added a little storage on the side of the fang. I also added a bar with M3 threads inside to fasten the fans. It is still possible to mount a 40x20mm Noctua, as you can see in my pictures.
