They sell 12"x12" sheets. A .040" thick sheet is just over 1mm if laying them works??? a 12x12 is $12.30 USD plus shipping.
The .250" 12x12 sheet is about 6.35mm and its $52USD!
Yeah, anyone willing to sell a kidney or trade one of their offspring? I wouldn't attempt to multi layer 1mm thick sheets. The chance of an air leak is too high...
