Hey everyone - I worked with @pacificmeister to create a fully parametric design in Fusion 360 for a propeller and duct combination.
Here’s a video demonstrating how to make changes to the model and how it was built: https://youtu.be/gVNXL8XpMAg

The design is certainly not perfect, as the airfoil profiles are really just rough estimates at this point. I tested changing most of the important parameters, and the model doesn’t seem to break. Hopefully this is valuable to everyone else, and at the least a starting off point for other builders!
