Parametric TPU Strap Generator

🌀 Parametric Spiral Strap Generator for TPU Belts
This OpenSCAD script generates a customizable spiral-shaped strap, ideal for creating flexible TPU belts, coiled tension bands, or modular fastening systems. The spiral is built from a continuous ribbon path, ensuring smooth unrolling and consistent thickness throughout. Designed for precision and adaptability, it’s perfect for prototyping wearable components, cable wraps, or deployable structures.
🔧 Adjustable Parameters
- spiral_width: Defines the strap’s thickness in millimeters. This controls both the printed width and the spacing between loops.
- spiral_radius: Sets the maximum outer radius of the spiral. The entire design fits within a square area of 170×170 mm when set to 85 mm.
- turns: Number of spiral loops. More turns increase the total strap length while keeping the footprint compact.
- segments_per_turn: Controls the smoothness of the spiral curve. Higher values yield cleaner geometry for slicing and printing.
