// By default the spline is created as a polygon with `2n` edges and the radius is the outer radius to the unchamfered corners.
// For large choices of `n` this will produce result that is close to circular. For small `n` the result will be obviously polygonal.
// If you want a cylindrical result then set `crop=true`, which will intersect an oversized version of the joint with a suitable cylinder.
// Note that cropping makes the most difference when the tooth count is low.

// The teeth are chamfered proportionally based on the `chamfer` argument which specifies the fraction of the teeth tips
// to remove. The teeth valleys are chamfered by half the specified value to ensure that there is room for the parts
