Let the prototyping for the next water cooling setup begin 
where did you buy the water jackets from?
@Cristian_Nicola banggood
considering that the thermal transfer for water is quite good and temperatures are likely to be quite low, would plastic fittings save weight and accomplish the same result? Even a plastic enclosure would likely not have temperature issues? Should there be fins on the water immersed portion? Is it possible for any hot end to be too cool?
The anodizing looks great!
You can’t water-cool below room temperature with a standard-setup. So, too cold is not a problem. Internal fins aren’t needed, the setup is overdesigned already. I wouldn’t trust printed parts there, but this is maybe an option for tinkerers.
I am curious why water cool it at all? Isn’t that whole cooler heavier then say an e3d with a fan. Sure looks heavier. So is the point to be able to run hotter, faster?
for me it is: silence. For others it may be a heated chamber or other things…
