Vacuum formers are still fairly rare in our community, so it was a surprise to see that in the 1960s Mattel marketed one as a toy. It used a hot plate to mold plastic sheets into various shapes. The design was updated by Toymax in the early ’90s to use a light bulb heating element to make car bodies, like some sort of manly Easy-Bake Oven. The home-built machines we’ve seen are a much larger scale. In 2005, we posted [Ralis Kahn]’s version that employed an electric grill as the heating element. [drcrash] has since built on those plans, hoping to develop an even cheaper device.
