Experimenting with 3D printing functional propellers for RC

I've made some significant updates to my propeller design software. It now uses spline based geometry allowing me to quickly create some intricate shapes that scale with adjustable resolution. The geometry for these 3D printed propellers were automatically generated.

I need to figure if I can generate a business model for this design work that a) will generate income and b) won't get me shunned from Open Hardware or maker groups...

This is fantastic work. In fact I'm attempting the same thing. I'm writing a python script using the Rhino3D plugin to try and maximize efficiency for an extra light drone of my own design. I'd love to know more about how you wrote your software. What are you using? How did you structure it? How complex? Could you offer any advice on some stumbling blocks I'm finding?

Thanks in advance and keep up the good work,
Nicholas

p.s. I think you could offer free .stl files through a website using an open source OpenGL API and collect ad revenue.

Hi Nicholas,

I wrote the software using the Blender API and Python. The software is Free Software, check out the project page and download the source code: http://www.circuitgrove.com/projects/turbomachinery-design-toolkit

I'm not quite sure what you are asking for in terms of advice... If you want to know how I did something in particular, I'd be happy to discuss.
