Wow. This has got to be the way forward. So light and compact.
Questions:
- are there no PTFE liners in the tubes?
- I assume you are using 1.75mm filament, are the stainless tubes 2mm id?
- are the tubes a press fit in the hot end?
- I can't see what the central tube does. You are using 3 colours, right? Looks like 2 stage heating element. Is it soldered to the brass fittings on the other tubes or just heated by contact?

Thanks Xabbax. I visited your website.
I like the welding nozzles idea. Couple of further questions:-
- what is the centre hole in the heating block for?
- is the water cooling by natural convection or forced circulation with a pump? If so what kind have you used?
I would like to build one. I have tried twin nozzles with a Bowden setup on my OrdBot. The problem was getting them level. Your nozzle would eliminate that.

Thanks Xabbax. Yes, can you post the OpenScad code. That would be useful.
The tubes look to be at about 45 deg. Is that right?
