Mattell’s Vac-U-Form Was the 3D Printer of the 1960s

Back in the 1960s, this Mattell toy was hot—literally. The Vac-U-Form let kids mold shapes out of heat-softened plastic by sucking it over a form, just like RC bodies are made. Various forms were offered, including trucks and planes. The Mattell Vac-U-Form is still a sought-after item on eBay—scale modelers use them to make and duplicate clear canopies and all kinds of stuff.

A heated plate softens the sheet plastic, then you flip it over the form you want to mold. Pumping a lever sucks the softened plastic over the form.

If you really want to go for it, you can make your own vacuum forming table big enough for RC car bodies and make your own body forms, like this guy:
