Axial Flow Compressor

I design cool gadgets in 3D CAD at Texas State and experiment with additive manufacturing. A dowel stuck in this device, could it make it fly? It's a 3-inch diameter, hollow sphere. Three to four self-tapping screws are threaded into the 1/16 inch holes for added stability. The curved shape and design resemble aircraft wings and have a moderate sweep angle. I'm not an expert in fluid dynamics, but it looks good. I'll be printing one soon - if you print yours before me, let me know how it performs. Instructions: Print this device on the flat side with no holes facing upwards. It was scaled for printing at 3 inches along either axis, so adjust accordingly. Make sure to use uniform scaling. The STL file for printing is already set up for best results, maximizing both length and angle limits.
