Parametric Wind‐Whirl Generator

What it is
A fully‐parametric OpenSCAD script that generates elegant, spiral “wind whirl” sculptures designed to press‐fit a bearing. You get a hollow hub for the bearing plus twisting arms that catch a breeze, all customizable at runtime.

Key Features

• Hollow Bearing Hub
  Precisely sized pocket (with clearance) for a  bearing.
• Adjustable Spiral Arms
  Choose how many arms (e.g. 3–12+), how long, how wide, and how much twist each one gets.
• Aesthetic Chamfers
  Convert each rectangular arm into an airfoil profile by chamfering each leading or trailing edge—tune the “wing” shape for maximal wind capture.
• Custom Wave Patterns
  Add sinusoidal “wiggles” along your arms for sculptural flair. Control amplitude, frequency, start/end along the arm, and offset phase.
• Outer Cutoff & Ring
  Clip your entire sculpture to a fixed outer diameter, or surround it with a cylinder “ring” for a framed, contained look.

Use Cases

• Wind Sculptures & Kinetic Art
  Perfect for yard or patio decorations—place on a stake, hang from a tree, or mount to a wall stud; the bearing lets it spin freely in any breeze.
• Functional Turbines & Fans
  Prototype small, low‐speed fan blades for ventilation or cooling; adjust twist and profile for maximum airflow.
