Parametric Cookie Cutter

Inspired by whowhatwhere\'s cookie cutters, I decided to take a stab at making a more generalizable cookie cutter pattern.

This OpenSCAD script has parameters for the standard dimensions, but it also has a \"primitive\" module which you can replace with any scalable flat shape. It creates a wall in 3 thicknesses -- a thick lip at the very bottom, a sturdy wall for most of the height, and then a single-filament-width tip at the very top.
