Here's a prediction - just like the past few times these have been posted, the thread will soon fill up with people saying they're impractical because they'd be too hard to cast, too expensive to CNC mill, and too weak if 3D-printed, because it hasn't occurred to them that you cast the prop hub, forge the blades, and weld them.
