Coordinal is a simple tool to create coordinates for cross sections for manipulation in OpenSCAD. It’s my first experiment with Paper.js. The paperscript is compiled from CoffeeScript.

Take the output coordinate list and use it with rotate_extrude and the like.

For example:

rotate_extrude($fn=100) polygon(points=[
  [75, 280],
  [108, 360],
  [162, 402],
  ...
  [75, 280]
]);

I’ve printed several of these revolutions on the MakerBot Replicator 2. Typically supports will be required for printing to avoid collapse with some of the angles.
