Modified Helical Darrieus Wind Turbine Blade

Relevant publication: http://www.iaeng.org/publication/WCE2018/WCE2018_pp586-595.pdf
An improvement over the Helical Darrieus Wind Turbine Blade, according to same aerodynamic principles as https://grabcad.com/library/rear-wing-formula-one-dimensions-2, https://grabcad.com/library/modified-10x4-7-propeller-1 and https://grabcad.com/library/modified-rotor-blade-1. (all are my entries for the https://grabcad.com/challenges/extreme-redesign-engineering-post-secondary)
The white blade is more aerodynamically efficient than the black one.
I have no access to a 3D printer, my engineering judgment says these blades must be printable without any problems, if flipped perpendicular to the rotational axis.
Baseline blade files are also attached for fluid dynamics analysis.
