Yes, but, but, but... I don't claim to be a carver,
never mind one who could turn out a positive model
that must be this small (1" x 1" x about 1/8" or if
you prefer 25mm x 25mm x about 3mm). 

The goal here is to create a mold that can be used to
cast pewter case badges. Now that sort of mold can be
made by machining a block of aluminium (or other metal
with a melting point MUCH higher than pewter).
Alternatively one can use wax and/or FIMO (a type of
clay) to make a positive image, then use a heat
tolerant silicone rubber (or some types of plaster or
sand) to make the mold.

So, if nobody knows a cheap route for CNC Machines to
directly machine the mold, is anyone comfortable
carving a good looking Tux in a 1" x 1" (25mm x 25mm)
space?
