Hi formpig :)

There is a tessilation-patch of povray
http://jgrimbert.free.fr/pov/patch/tessel/index.html

But you still need to convert the raw-Data to stl.
Stl-files containing information about the specific size of an object. (Inch,
mm, cm..) Povray have its own units, but it doesn't referred to an specific
length.

You will need to use a converter and (best) another application, like Blender,
to import the objects, scale it to its right size and export them as .stl

Ps.: I wasn't able to compile the patch statically under cygwin. If you be able
to solve that problem, I would be very happy for a link to the executable, so
that we be able to use it under windows too.

Good luck!

Holger
