So we all heard this MIT toroidal propeller thing, I decided to make a parametric one so you can experiment with your own parameter.

Update 12 Feb 2023 Just made an updated version, please find the file marked as v2, you can compare it with the original version Updated features :

• Center holder cylinder has a separate diameter config
• Parametric numbers of toroidal prop
• Overlapping toroidal props are fixed
• Adaptive cw ccw based on extrude twist value

Update 13 Feb 2023 Someone requested a babyhawk version of this propeller, so you'll find some new files here Updated features :

• Code refactoring, module based to simplify & reduce repetition. Rename some variables
• Parametric side hole for screwing your prop, default parameter compatible with the emax babyhawk, you can modify to t-motor style as well
