do you have any way of giving the walls of the pins a pattern for greater surface area on your engraver ?
what is the base plate thickness

I did this on my personal CNC mill not the engraver at work. The engraver isn't capable of this. I might be able to find a roughing endmill (see pic attached) that would add mini channels to the walls of the pins. Something I have thought of doing for a long time but just never bought the endmill to do it.
That pattern is possible but I am not up to doing it. It would add about 10hrs (literally) to the milling process on my mill. But it is possible. The way I have it setup now would be hard to beat with that pattern thought. The flow rate through this thing is unreal as I have it. With that pattern flow rate would decrease, the pump would work harder and I think that would offset any gain. Even the 170GPH doesn't even flinch pushing water through it. That was one of my main goals when I designed it as back then (2 years ago!) high flow blocks were all the rage. And I am going to start going back to higher flow rate designs simply because I would rather use smaller and lower GPH and cheaper pumps in the future even if it causes a few C warmer temps.
As of now the base thickness is .175" or 4.445mm. and the overall is 0.375"or 9.525mm. The top will be .25" or 6.35mm Copper plate which is almost done. If the results are not as I expect I might shave the base down to .125" or 3.175mm but I do not think a design like this will benifit from a thinner base than that as I want the heat to spread on this one a little as opposed to the other designs where I try to keep the heat staged in the area over the die.
