Updated for different petal angles, depending on what your printer can handle in one piece -

It seems that once there is some roll back, it's actually pretty hard to make it seriously degraded. There were even attempts to put the waveguide almost against a baffle behind it (or to "dive" it through), without much degradation. Not something I would do or like (the smoothness of DI probably suffers at the lower end) but obviously it's quite immune - again, once there is some rolling back.

Great! Would it be possible to add some guide "holes" to the parts? Like dia 3mm and depth 5mm or something. Came to think about this as I happen to have 3mm wooden BBQ sticks that I have used before to align stuff using holes for M3 screws.
Is there really a need for that in this case? Such details can be a pain to print accurately and can easily cause more trouble than they solve, IMHO. I'm not very keen on the idea.
I would first assemble the petals, making a full circle and then attach it to the throat piece. Shouldn't be too difficult.

Those would be grat with these:

I hadn't any particular driver in mind, other than the size. The throat angle is 19°, which should work fine with just about anything out there.
I don't know the exit angle of the Peerless DFM2535R00-08 - it will hardly get any better than that, IMO. B&C DE500 was also exemplary. But it's all much more similar than different.

I'm sure this is obvious, but note that you can increase the size of a horn that's printable by just rotating it 45 degrees on the bed.
IE, if your print bed measures 200mm x 200mm, you can print a 282.2mm horn on it by rotating the horn 45 degrees.
Yes, I know. But with the thingy printed for adhesion the 150mm is really more like 140mm. Not much room to rotate.
Well well, I stand corrected. It seems to be possible to print the 180deg petal after all.
I´m a total noob whith 3D printing. Studying the slicer slightly more I found a way to fit the thing in to the print area. I didn´t relize that there´s actually 400 parameters and different ways to position the part on the print bed. My history in 3D printing is about 4 weeks . . .
