Build Your Own Vacuum Form Machine

This detailed guide complete with images, build/circuitry diagrams, and links to manufacturers explicates how to build your own "Vac-U-Form" machine. If you're not familiar with this, it's basically a device that lets you turn out a hard-shell plastic replica of about any 3D object. So you could, for example, build a prototype out of wood or foam and Vac-U-Form a plastic copy of it like the ones shown in the image to the right.
