I've been reading books on vac-forming and they "usually" stay with about 1mm max. That's for seed reasons
mostly. If you just let radiant heat soften a sheet for longer, thicker works. When the corners of a tray
are rounded and like a natural shape of a softened sheet of plastic pulled by vacuum or pushed by air,
the plastic need not be completely sagging under its weight before applying vac (and sometimes low pressure also).
The rubbery soft plastic will form into such a rounded shape. I think 2mm plastic would be a low risk experiment,
from what I've read.
