The gap at the throat (if I'm seeing what you mean) should pull together when you tighten the bolts that hold the two halves together there. At least it did on mine.
Thanks for the heads up
My new printer should be in by the 27th and I’m going to do all of the test prints and get it right. I got the one with a 300x300x400mm build size
that is I am planning to do.
V6 printing is in progress. Could the ports place on the size doable? I kinda prefer the V6 because they are smaller.

That arrangement what I had in mind for the fully printed waveguide.
The V6 isn't intended to be smaller -- it's meant to be larger, as it's only a horn 'stub', to have plywood walls added to the size desired. I was going to make one 5ft (1.5 m) wide, but never did, as I have no place to put such things!

What are we looking at?? Can't tell what these plots are, can't expand enough to read the text...
Here's the latest file, a version without the woofer mounts or ports. I think the woofers might work better (directivity meet up with the mids better) if they exited a littler further out horizontally. Right about just past the edges of the horn. Idea is to mount the woofs inside, facing toward the outside, exiting through vents on the baffle just to the sides of the horn. Never tried, btw, so just an idea. And should be lots easier to print, too.

Size: the picture is shown on a 300mm x 300mm print surface grid. Count the squares, should allow for a good estimate of dimensions, I don't have the info anymore (I think it's something like 19"x15")
I could not edit for some reason, sorry!
Trying to squeeze to about half size.
Internal dimension 20X17X9=3060cuin
Speakers, X-over, 2 braces~600cuin
Net volume=2460cuin=1.42cuft
1 round port 2.68" diameter 1" length, I might put it at the rear.
Box tunning=60Hz, 1st port resonance ~6.7KHz (should I be worried?)
F3= 51Hz vs your of 39Hz base on my calculation.
Thanks,

Oh I never actually *finish* anything lol
In the span of 27 years doing this hobby, I think the longest I've actually had one of my projects as my "main" speakers has been about six weeks.
I like building things more than finishing things.
But Bill's speakers are great!
I am building the Metlako, will see how each differ in sound. I think Bill's built is like PA "sound" while your are for "HiFi"
I am for smaller horn that behave like big horn.
