Which code are you using and how small do you want your capillaries?

The XXX blocks I only intend to make in silver for the bases. Am giving very serious thought to putting copper tops on them though just for strength as I don't really want to risk another repeat of a bad polycarb batch resulting in cracking tops. This would also allow the block to be thinner, as in 16mm high instead of the current 20mm.

Am giving serious thought to calling such blocks "Cascade XS", and dropping the XXX code-name moniker.
Which finite element code are you running? ANSYS? or NASTRAN? OR ? and have you considered using self assembled or lithographically etched tubes?
