To those following and interested, I’ve released a few 3D printable propellers. Feel free to try printing them out and operating them. They aren’t fancy, or optimised. I have not benchmarked their performance yet. They were designed using basic propeller principles.
Check them out but please be careful not to hurt yourself or anyone else. Use at own risk and take normal safety precautions as you would any propeller.
