Re: Low cost material



How about a thin aluminum *** like a cookie ***? Punch indentations
in it to form the pockets you need. A muffin tin?

Fiberglass/epoxy; you want a material with a softening temperature
considerably higher than 200F to prevent permanent deformation.

Or a thick aluminum plate. The heat capacity of a particular volume of
AL is only about twice that of the same volume of PMMA.
