All parametric Helix, Propeller, Blade Generator creates versatile propellers for planes, helicopters, boats, and more, customizable by size and number of blades. A new version is available, now featuring optional blade tips that reduce low-pressure losses and turbulence on the edge of each blade. Your contributions can further enhance this tool's capabilities. Download designs from my Pinshape portfolio at http://pinshape.com/users/27920-jsirgado or access the OpenSCAD file to customize and modify all features. Below, you will find instructions: Examples are provided in both STL format with a normal (NR) and mirrored (MR) version of each helix. This setup is particularly useful for quadcopter applications. Each sample includes small notches on the top/bottom edges of the blades, facilitating an easier print process. For improved printing results, consider using support material during the build.
