Loving the work of others, notably:

but wanting to verify the flow design (in simscale), I searched onshape and found this:
https://cad.onshape.com/documents/b98cd22c03a7a4e5655154f0/w/53716c81b348440ab5b15dad/e/50e625e6e930601d7ad8990e
which appears to be inspired by the original ring design above, so this thing is a copy and extension of that:

(if you are JACJR on onshape, let me know and I can credit you properly)
This is a work in progress, so far I have only made small modifications to the design:
thickened one wall of the ring
added a chamfer in a couple of places (or changed from a fillet on the bed)
modified the outlet to allow it to bridge the opening
sharpened up the trailing edge of the flow dividers
I have run a simulation (though not since my modifications), and it looks pretty good, there is a big region of low flow/pressure where it might be good to split the ring, and it does look like the direction of the flow is a little bit downwards.
Progress: Okay I don't know what hot end the original design is for, but it does not fit my stock ender 3 v2 neo (ring too far to the right, and the drop is too short) - so I've fixed that in the newly uploaded file. The print came out much better than both the original thing, and the design as it came from onshape.
