Everyone thinks the big secret is in the aerodynamic duct. It also counts, but it does not use a fan for quiet, strong air flow, but turbine. Look at the Dyson videos. Helix3D has published one such thing and has been banned. So a smooth fan does not make the right flow to start air multiplication. There is not enough air and low pressure. So you're better off controlling your PC fan.
Everyone also ignores the importance of aerodynamics in the smoothness of the surface. During printing, grooves are created which, when crossed, slow down the flow of air with micro turbulence. Anyway, the weak airflow is further weakened. (Dyson does not accidentally shine)

Take these into account before wasting plastic.

You are correct about the main issue being a lack of pressure from the radial fan. I have a second, independent design that is a turbine compressor https://www.thingiverse.com/thing:2771339. If someone wanted to experiment to see if the increased pressure made a difference, they could snap the two together.

I don't think that would help. I have a 75mm x 30mm one I tried, and even at 16V it didn't really move that much air and didn't seem to have much more static pressure.

Is it possible to drive this using a radial fan (e.g. 5015)?
