OpenSCAD wave vase designer

This thing is intended for OpenSCAD users who want to design smoothly curved vases without waiting for long rendering times. It includes the OpenSCAD code, the STL file for the default design, and the OpenSCAD customizer file wave_vase.json with nine example vase designs.

The OpenSCAD code generates a curved shape in 2D, then uses rotate_extrude() to make it 3D. The result is like a linear_extrude() of a circle() with $fn sides, except that instead of extruding along a straight line, it extrudes along a sine wave. One advantage this code has over linear_extrude() is that the walls are the same thickness throughout. When you use the scale parameter with linear_extrude(), wall thickness varies with height. The big advantage of this code is that it renders at least 100 times faster than rendering the same design made using 3D objects.

This program has nine parameters that you can modify to change the shape of the vase:
height = height of the vase
radius = nominal radius of the vas
