I saw this guy, Richard Jacobsen, demonstrate how to make a vacu-form mold using parts in total that all costs less than $300.
He was a super nice guy, and his demonstration was perfectly clear. All you need is a heat source, plywood frames to hold the styrene (plastic), a rubber mat with a hole in it, and a shop vac.
It worked brilliantly.
