It's awesome that a more compact duct gives such encouraging results ! It's probably lighter too, did you make input shaping comparisons ?

I was playing around the crown duct, and found a 360 outlet at the bottom performed a little better than just 6 outlets, but that was using 5015. The cpap style might be different.

I don't think the original crown duct can work with 5015/5020/axial. It needs some good pressure to perform. In stock form is lackluster with regard to flow. But no idea on it's effectiveness printing and at what speed. I may try a wedge design at some point, but I want to play with this duct a little. I have already added the 'valve' function of Valvnator and reduced the number of ports to 4. I need to find out how it flows 360 before I Can add more. In my mind, 4 is all that is needed + the valve slit.

​@@MrRocksaltive used a similar design 360 duct with decent effect with a overvolted 5015 fan, but found the side directly opposite from the fan would still suffer when reducing the fan speed. Having a fan on both sides helped a lot. Might need to try it with 2x roborock cpap next.
