CR-10 / Ender 3 Dual 40mm Volcano Part Cooling Fan Ductinator

This is my dual 40mm part cooling fan setup inspired by the Volcano heat block design: https://www.thingiverse.com/thing:3594440. For those who may be unfamiliar, Volcano heat blocks fit directly onto the standard CR-10 heat break. In my case, I was using a Micro Swiss all-metal hot end and had recently installed a Micro-Swiss titanium heat break, which led me to experiment with an E3D Volcano clone heat block. This unique setup is performing exceptionally well. My design logic centers around the idea that large fans running at slower speeds can move more air while operating quietly, compared to smaller fans running at full speed. For standard printing, I typically run the fans at 50% capacity. However, when I need to print quickly with a larger Volcano nozzle and thicker layers, I throttle up the fan speed for optimal results.
