So here is the long awaited run down of the E3D Kraken - A 4-Nozzle water cooled, all metal, plastic melting monster!
(Video complete with me in full hand waving manic teacher-mode)
Pictures below in comments.
So G+ Doesn’t let you post a video with attached images in the same post. Here are the images:
Are those standard G1/4 threads?
On which part?
On the heatsink - G1/4 is the default thread for PC watercooling, which would make it compatible with all of the nice (or cheap, at your choice) connectors.
Ah I see - on the prototype they are M8. In the final version they will be G1/8 (1/8th BSPP). G1/4 is too big to use here.
Well, better than M8 either way - G1/8 still is a fairly common size, so there’s a good selection of connectors and accessories there as well, for when, say, someone wanted to connect a Kraken to another one right next to it.
Anyways, awesome work!
Very cool. You have an expected price on that ?
Yes! I am tres excite 
So excited! Definitely let us know a price.
@Sanjay_Mortimer any joy with 4 extruder support in Marlin?
Do you have dimensions on the inlet separation so people could design a cold end for it?
Was going to get an E3D hot end but I want this for my Mendel90 ! I have projects in mind already that would use this. Awesome work … but how to control it ?
Now I call this plausible! @Sanjay_Mortimer you should make this features also into the single nozzle, lets call it V6. The part most interesting is making a PTFE tube go in the middle of the thermal barrier and a set screw for the cooling part to easily set your nozzle height.
Looks great Sanjay, I will definitely be ordering one when available.
Wow, one word. Bitchin! I like how you can align the heights of the nozzles. This is a problem with the replicator 2x at work at one nozzle can collide with the plastic the other prints. Great work.
Will buy for sure
Have you experimented much with radically different temps on adjacent nozzles? I would imagine a 270C nozzle next to a 170C nozzle would cause some issues with radiant and to an extent convective heat when they’re so close.
@Nick_Parker is imagine that the conductive heat would have more of an effect than anything else, and that is pat the heat break, so I’m thinking it should be fine. Raisin is only an issue for very large heat gradients and connection should be minimal unless there is fluid motion
