I very much like SNASA's Coaster - Printing in progress model, and whereas this model is not a remix of that fine work, it was certainly inspired by it. You see, the nozzle of that model is beautiful and prints perfectly, but >twitch</blink it does not look like my printer's nozzle.

Could I easily get it to look like my nozzle?

Turns out that NOOOOoooOOOOooooOOOooope!

Drats! >_<

Well, maybe someone has modeled the V6 compatible Diamondback nozzle (henceforth DBN, if 'ya know) … NOOOOoooOOOO Siree!

Double drats!!! >_< 
Ooommph! 

Fine! Been meaning to model something other than a cube in Plasticity. 
Sleeves rolled up, determined squinty look, I set out on them internets to find photos or schematics of the nozzle in question…

Triple dra-you know what, fine!- it's not worth the frustration.

I went back to the product page on Amazon. Heyhey! Pictures!

Holding a long crooked stick at arm's length, one eye closed and tongue hanging out, I got to designing basic primitives/shapes to try and build up something that could pass as this thing.

Did it have to be so curvy/bendy !?!
-(sigh)-
I am committed … I am committed … I am committed … [as Plasticity whispered  “yeah, bud, let's test that conviction!”]

[enter inspiring 80's themed upbeat rock music cut scene montage of me thoughtfully nodding and learning about lofting, patching edges, making new solids, revolving curves to cut/trim other volumes]

- Shoot, how do you make the threads?!  Pixel Fondue's 60 second tutorial to the rescue. 
- Easy peasy! Watch me bang these out in less than a minute …

“Boolean function failed”“Boolean function failed”“Boolean function failed”“Boolean function failed”“Boolean function failed”“Boolean function failed”“Boolean function failed”“Boolean function failed”“Boolean function failed”“Boolean function failed”“Boolean function failed”“Boolean function failed”“Boolean function failed”“Boolean function failed”“Boolean function failed”

-forehead slowly and rhythmically bangs on keyboard … please Plasticity, please … 

“Boolean function failed”

Ok, it took a few tries and the better part of an hour to do the threads. Nothing exact about them. I was going for approximate dimensional look/feel that would have ~8 apparent revolutions (as per the source material: Amazon product listing photos).

At long last, the listed STL was achieved.

Mind you, I did find the Diamondback logo and converted into an SVG and thought I was going to be so clever and emboss it on in PrusaSlicer, along with the two “4” and “.4” designations (on the tip and main body of the nozzle). 
But 1) PrusaSlicer don't like what I serve up

and 2) I don't have exact matching fonts for the depicted numbers.

Having lost the drats count for now (somewhere in the hundreds), I resigned myself to publishing what I have so far, and hope it is of some value to you.

I will come back to this model and finish it out. But I may need your help for that. 

So, Point of Discussion and Action Call: I have no idea what the internals of this thing look like. If anyone has a cut-away schematic/diagram, I would love to know so I may go back and hollow out the internals appropriately, and re-post the file (perhaps along with a nice cut-away model - which I know people can do by themselves with a negative volume box in PrusaSlicer-) to showcase it, so that it can serve as a 3D printing educational model.

[Printing instructions: I have not printed this as of yet. I am sure to, once internals are  finalized and will post recommended settings. Can't imagine they'd be anything too far afield  of the usual; and I mean, doesn't that also somewhat depend on your choice of scale?]

It is getting late, and I have other (actual) pressing work to get to.
Keep doing the productive things that compel'ya. 
What choice is there?
The alternatives lead no place good.
