Testing 3D Printed Water Pump Turbines - Which One Is The Most Efficient?

Testing out four 3D printed turbine designs. The water pump is powered by a 775 electric motor and power supply is a power drill battery (3.0ah NiCad). In this video, u will see building tutorial and after that testing. Results were really different from what I personally expected, I think this project was really useful and educational because the turbine what I was thinking as most powerful was actually...well u see in the video.
Every 3D printed parts that u see in this video are printed with PLA filament and with 0.8mm nozzle. Free STL Files included as always.
I hope u did like that video and u will check out my other projects.
