You saw the wooden topo models in the infeed/outfeed forum. We decided that it would be fun to mold chocolates in that shape for Christmas presents. I tried the moldable silicone putty, but it was difficult to do and expensive. Vacuum formed molds seemed to be the answer. I made this very simple 6x6 vacuum former -

powered by my shop vac.

The only thin plastic around (it's Sunday and it's 2.5 hours to the nearest plastics supplier) was an empty plastic water jug from the distilled water for the batteries. It's 15mil HDPE. Very easy to melt - I used a heat gun. Here's the result. Exceeded my expectations on the first try.

GREAT idea!
I never thought about doing anything like that. I had a small Vacu-form when I was a kid. We used to make copies of die-cast metal hot wheels cars for our H. O. slot cars. I have thought about building one for larger things but, never came up with a good idea.
Thanks!

I always wanted one of those, but never got one. I'm SO jealous :-)
