OpenSCAD code to generate arbitrary gears with a truncated octahedron profile that is mapped to a sphere. The following parameters can be changed:
- gear_teeth_count: Number of teeth per gear
- gear_radius: Radius of gear at mid point
- gear_pitch: Distance between gear teeth
- start_angle: midpoint angle of the gear (recommended 0 - 80)
- clipTop: trim off additional bits extending above and below
- highTop: add additional height for gearing near the top
- num_cycles: number of gear levels (works best with odd numbers)
- height_multiplier: modifier to change gear tooth depth / height
- make_flat: make teeth with a flat contact profile instead of a spherical contact
- axle_type: type of central axle ("cross", “hole”, “keyway”, “none”)
- axle_diameter: diameter of central axle
- xw: line extrusion width
- extra_base_height: add additional distance to the base (needed for angles near 90)
- ring_gear: create internal / inverse gearing
