Model airplane prop for 7200 RPM HDD motor
thingiverse
Made this prop to fit a motor I pulled out of a 7200 RPM HDD (western digital - WD800JD) prop uses an NACA 2412 airfoil I used a real airfoil, but beyond that I didn't spend much time getting the aerodynamics correct, i.e. no consideration of surface area or angle of attack/twist. Just tried to make it look cool to see what my printer could handle. Havent spun it up yet because I dont have a driver for the motor, but I'd love to see it spin. Seems like it would move some serious air. Instructions Made this one in PLA 0.127 mm layer height. Support material is needed and unfortunately will scar the bottom side of the blades...unless you have better support settings than I can figure out...
