About this 3D model

The rotate_extrude command in openSCAD has fascinating posibilities. It can replace the potters wheel and the woodworkers lathe. All one has to do is draw a 2 dimensional profile of a clay pot or wooden bowl, convert it to a polygon, invoke rotate_extrude and a pot or bowl is produced. Here is a parametric program that uses the rotate_extrude command to make wine glasses, glasses, and bowls. Examples outputs are given below: 1. wine_glass.stl 2. drink_cup_5oz.stl 3. small_bowl.stl 4. cat_food_dish.stl The parameters that produced the above outputs are appended as comments to the openSCAD program make_wine_glass.scad.
