3-blade propeller with cone

thingiverse

I'm curious about the load capacity of this propeller, given that the original hub design is fairly weak. To better suit my needs, I've redesigned it. The blades need to be secured in place using thin CA glue. A drop of CA glue should be applied into the gap only after the blades have been inserted. Up next: Conduct a comprehensive stress test with precise measurements. **Warning:** Using this propeller in an uncontrolled environment is extremely hazardous. High RPM can and will likely cause structural damage, leading to explosive disintegration. Fast-moving fragments from the destroyed propeller pose a significant risk of serious injury to people or animals. Proceed with utmost caution.
