I am small box that is rather flimsy.  I want to reenforce it with plastic
or some other material.  So, there will be a strong functional box
glued inside of a pretty but non-functional box.  The max dimension would
be 3 inches or so.  Perf board material would be a pretty good thicknes and
strength but I don't have enough, it is expensive and it seems a shame to
use it for a non-wiring pupose.  Can anyone think of something off hand
from home depot / wally mart / etc?  Some common thing made of a thin (1/16
inch) rigid plastic that I can cut up?

A small piece of polycarb perhaps.  I may have some about that size around
here somewhere.  The stuff is very tough.  Pliant, but hard to puncture.
 You can also get sheets at Home Depot, but I don't know how inexpensive it
may be.

If you are handy with 3d, you could loft a box shaped to your requirements, then 3d print it out...

Perf boards before they become perf boards:

It's kind of expensive but it's very very strong, I used to use it to make
replacement parts for RC trucks.  I use it as a cheaper alternative to
carbon fiber sheets.

The only problem is it's very difficult to machine... the standard
perfboard beige stuff might cut on the laser cutter but I doubt the glossy
black version will.  CNC machining also takes a bit of patience and an
abundance of router bits.

What about good ole 1/8" plywood?  I love baltic birch plywood and it is
very strong and laserable.  You may even be able to find a scrap that would
fit your needs under the laser table.

Radio Shack sells good project boxes in a variety of sizes.  They're good quality ABS, come with both a plastic top and metal face plate, and are cheap.  I picked up the one below, which is 3x2x1, for under $3.

Or you can always cut out a box on the laser cutter.  They sell 8x10" sheets of .080" acrylic for about $1 at Lowe's.

As for cutting boxes on the laser there is an Inkscape extension on the
computer that makes fingerboxes like this...
