*these spinners all currently spin CCW (tractor) if viewing the plane from the front. To reverse simply mirror the print in your preferred slicing software.
THESE DESIGNS ARE PRINTED AND USED ENTIRELY AT YOUR OWN RISK
obviously high RPM is dangerous and can cause shrapnel in excess of 120 MPH (depending on rpm, could be even higher)
Use these prints at your own risk, they work for me and my application spinning at 10K rpm, Idk if they will work for you and make no claim to safety.
The master airscrew 3 blade props had a wider diameter face and would not mount in the included STL files from 3dlabprint, so I designed these from scratch to work with the propeller I have.
Also using the D4023 850kv Brushless Outrunner Motor
I also included a 2 blade version, the configuration I am using these requires a bolt between the propeller and spinner (the propeller does not mate directly to the face of the spinner)
However your application demands shouldn't be too difficult to setup depending on the propeller you have.
the propeller is not my design or original work https://grabcad.com/library/rc-airplane-prop-and-mold The propeller belongs to Spencer Stromberg, I made some basic edits to the file for my own use check out his stuff on grabcad
Layout on bed as shown. Simply copy, mirror, and print. Print on HQ settings, low layer height, low speed.
Had issues printing with Cura, slic3r worked best for some reason, always verify layers are printing as desired.
