Parametric Vase

Yet another parametric vase design. Pretty simple OpenSCAD file, I'm just learning how to use polygon() and linear_extrude()

Given any number of sides for the polygon, make a vase with a user defined height and radius. You can also enter a number of twists for the shape.

openClose parameter will make a spike if set to 0, or a shot glass or bowl is made > 1.
