I think the thickness of a normal sized pyramid wall is a little under 1/16".
I just measured some pieces, and this is a more complex issue than it seems. The wall thickness is about 1/16" as you say, but the *rims* of the pieces are slightly thicker (probably for mechanical reasons). The rims are about 3/32" thick. -- Elliott C. "Eeyore" Evans eeyore@xxxxxxxx
