8 Blade stubby remix.

thingiverse

I was blown away by the 4-blade turbine design. I decided to take it to the next level by scaling it up slightly, adjusting the attack angle for better performance and adding four more blades. To match my motor's specifications, I redesigned the hub and increased the hole size. Printing at nearly 100% infill allows me to drill out if needed later on. In an ideal scenario, I think the front of each blade could benefit from a scoop or hollow area to further boost efficiency. Nonetheless, this design is already looking solid as it stands. Big thanks are due to morrowwm for creating such a great starting point!
