Beskrivelse

Looking for Propellers? Look no further. This OpenSCAD script generates fully parametric propellers, fans, and rotors — from airplane props to drone rotors, boat screws, cooling fans, pullcopters, and more. It uses real NACA 4-digit airfoil profiles and aerodynamic planform laws to create blades that are not just visually realistic, but also functional. The script is based on the original work of Alex Matulich, rewritten using BOSL2 and enhanced with improved performance, additional controls, and well-structured parameters for easy customization. Big thanks to Alex for laying the groundwork. Click Customize to start generating your propeller. 🚀 Quick Start Define Your Propeller Begin with the essentials: set the number of blades, overall diameter, rotation direction, root size, and pitch. Customize the Shape Fine-tune blade geometry with chord modes, NACA airfoils, sweep, fairing, spinners, shrouds, and hub/shaft options. Render and Export Generate your propeller at the desired resolution, then export it for slicing and 3D printing. Always test new props safely! ⭐ Features Full Customization Control every aspect of the propeller. User-Friendly Well-structured parameters make it easy to design any style of propeller. Aerodynamic Accuracy Real NACA 4-digit profiles with elliptical tapering for functional, realistic blades. Precision Modeling Clean geometry and adjustable resolution ensure reliable, accurate results. 3D Printing Ready Fairing, trailing-edge thickness, and built-in safety tips for robust prints. 📘 Notes & Tips Airfoils & Shape Blades are generated from real 4-digit NACA airfoil profiles, blending from thick, cambered roots to slimmer tips. This provides strength at the hub and efficiency at the tip. You can explore and preview airfoils here: AirfoilTools – NACA 4-digit.
