My friend, Barry, isn’t that far from you (Thetford)
He’s made various home built items, Tune Anima copies, large Inlow Sound papier mache horns & the mould plug for them etc.But hasn’t committed to a printer so far.

Here’s a happy USA DIYaudio’er with a printed throat section and plywood SH60 larger section hybrid!
Using the Peeless DFM-2353 comp driver.
The MF drivers look further away from the LF drivers than on my effort though.
Guess they are still 1/4 wavelength difference.

A 790x520 horn is an annoying size for a 256x256 printer, you’d have to cut it into quite a lot of pieces. This would entail a fair bit of design work, which might not be trivial when you’re starting with just an stl model (rather than an actual Fusion file).
If he’s paying the £100+ for the model, it might be worth asking for a version that can be printed in pieces.
I’d rather model from scratch than import an stl and have to work with it in Fusion. Andy uses different modelling software which might make this easier.

Came across the original post that warned of PLA in hot conditions.
Average UK lounge is not subtropical USA though.
Yeah the original design requirements are very different from UK home use - weather, direct sunlight, wild temperature fluctuations and very high SPLs. I think that PLA will be fine, and I imagine that single drivers won’t be a problem either, but then you’d have to design it yourself!
I guess the only risk here is if they get direct full summer sunlight - forgot to draw curtains / blinds scenario. South or West facing rooms, patio/bifold doors etc.
First foray into printing a horn. I can’t take any credit at all. The stl file was sent to me as a copy of the Altec h808 and the printing set up by the technician in the workshop.
To fit the height without having to glue together about 7mm had to be chopped from the length of the horn section. Decided to take it from the large end rather than the smaller section that goes into the throat.
What would the conscious be in printing a final version. Keep the length and glue together. Remove the 7mm from either end or about 3.5mm from both ends?
Then onto material. What would be the ideal choice? I’ve seen carbon pla mentioned as a good material.

I have just started on a new 3d printed horn a collaboration with a mate of Guys
We may have to outsource the 3d Printing - Not sure yet.
Tis a large frontage ATH horn at 790 × 520 mm Kudos here for the design goes to Marcel Batik

Interesting Andy, certainly be interested in the smaller Opus 12 (Op.12.25) or the Tritonia S or XS. 
I have some models of the smaller Tritonia somewhere
Happy to knock one off for you?

Then there were two sections. Need to commit on material and colour and then get a pair fully printed.
