Sprout Lamp CNC lens form

First generation lens form freshly primed. While urethane foam is not an ideal material to construct a vacuforming buck from, it was fast to machine, free of directional grain and post finishing consisted of 10 minutes a form with sandpaper. While I much prefer Renshape and laminated MDF as my tool construction material of choice now, it was an interesting experiment in just how rapid and low cost I could make tooling construction.
