Parametrically designed 3D printed propellers anyone? In the picture is a 9x6 prop. I’m travelling right now and have some downtime so I decided to work on this.
This is an extension of the Turbomachinery Library I wrote a while back. It’s coded in Python and uses the Blender API. Currently limited to NACA4 airfoils. WIP.
Are you willing to share your code? I would like to have a look at it.
It’s hosted on GitHub under the AGPL license: https://github.com/CircuitGrove/DuctedFanDesignLibrary
It’s early on in the dev process. 
To use the code you’ll need a bit of Blender experience. It’s not ready to make useable props yet, but it’s almost there! I’ll probably get around to printing my first prop in 1-2 weeks when I get back home.
I’m going to make a separate GUI for the propeller and the ducted fan soon. Right now it’s all on the same panel. The propeller section is at the bottom of the panel.
