I had a problem with temperature control and needed a solution to get me to the next step. This was the perfect intermediate solution thanks to everyone who contributed to this and made it available to me.
I only printed the right-hand duct since I only needed to print one part to complete the dual outlet ducted fan setup. It printed beautifully and the glass build plate I recently installed allowed for perfect delamination.

I am impressed with how well this turned out. Fitment can be a little tricky around the sides of the cooling fans. In the case of my Wanhao's fans, the grille's mounting screws were tightened to the point that it deformed the side of the fan housing and I had to remove the grilles and trim the deformed material off. I was also unable to put the grilles back in place with the duct mounted.
