Since we have to have the walls there, we may as well make use of them in the conduction element of the cooling of the block to allow heat somewhere to go in extremely low flow scenarios otherwise the design will suck at low flow when the impingement effects start to lose their power.

But that's incedental not designed for right? 0.25 is the thinest you could safely go I'd imagine(Cu IS soft!
). I thought about using brass and having 0.1 walls, 1 or 1.5mm cups to make the 'secondary' heatpath negligent?. Drilling straight through the brass and using copper 'foil' (0.2mm) for the bottom (you can buy it in varying thin gauges from RC/hobby shops I believe). But I don't know how 'fine' you could go without it cutting through the Cu when clamped?...
PS. I'd use surgical steel syringes for the jets. Not that I could ever make this (to 0.1mm accuracy) but it's good to dream
...

Lee, Id love some 3mm copper. Cutting that 10mm stuff across the middle is a bitch!!
