Twisty vases via customizable polar graphs

thingiverse

This is a customizable wavy cup or vase. In the Customizer, you specify polar graph formulas for the bottom and top, as well as a formula for varying the diameter, and a twist angle, along with the wall thickness and the bottom thickness. The design may not work if your graphs have sharp edges. The OpenSCAD file uses my tube mesh library and function parser libraries. Updates: July 6-8, 2017: fix bug that cut off vases with too much flare; add slow-walls option
