Hi croky_b, i tried to do the same as you; use foam to make molds for vacuum forming. I have some questions about it.
- Where do you find the model in 3d format and how is it scale?
- Which program you use?, I use normally Autocad and Rhinoceros.
- Which is the thickness of the layer of foam? I have problems to drill layer more than 3 cms. There is not drill long enough?.
- Have you think about how to protect foam against hot during vacuum forming?, it probably melts.

To many questions, to many work. Laughing

Your work looks lovely, well done.
