Would it matter if I use steeper slope on crossover?A 4-5" shallow waveguide don't have much loading/directivity control down to 2 kHz and below but better than a bare dome without wg.
This will be active crossover so have flexibility there
Remember you'll be crossing over from a mid driver with some beaming at the top of its range, into a tweeter dispersing much more widely at those frequencies. so the indirect sound making up a fair bit of what you hear will have a step transition from one driver to the other. Unless the radiation pattern of both drivers is similar at the crossover I'd recommend nothing steeper than 4th order filters.
If you are crossing at 3khz (even 2.7khz) the 5" waveguide will match the dispersion of the 5" mid well. The 5" waveguide will lose pattern control around 2.5khz or so, but that won't matter much if you are not crossing that low.
on this thread is see people using some sort back plate to hold tweeter.Is there a stl for that?

My first attempt at a 3D printed waveguide needed a bracket. It was easy to draw and did the trick quite well.
I did need a higher resolution model, but it was good enough for testing.
Previously I had CNC milled a waveguide directly into the baffle. For this I just used a block with some foam to hold the tweeter in place. It's not perfect but has held up perfectly well.

The reason I made both available is if you look at just the on-axis response, the phase shield version is better. But as you get off-axis it performs worse. I made both available so people can use the one that best supports their priorities.
5": 5.78 x 4.88
6": 6.78 x 5.77
I just noticed the oddest thing. When I download an .stl from my website and open it in F360, it is scaled down in some way. Maybe 1/2 as big. They still print fine since many people have printed this already. Interestingly when I download and open the .step version, the dimensions are correct in F360. Anyone know why this might be happening? Why would F360 incorrectly read an .stl that was created in F360?
Maybe metric vs imperial conversion?
I personally also need to convert stl from imperial to metric in prusaslicer. I guess the file format do not include the unit ...
any other waveguide that is similar dimensions as tw29txn
lenght and height.
want to use some cheaper aluminum tweeter for atmos. but baffle is already cut

I am planning an active setup using these WG and a Peerless/Vifa OT19NC00-04. From the repsonse shown in Augerpros's webpage, I only need to add a HP around 1.9Khz and nothing else.
Is this OK? The response is quite smooth.

Yes, it looks it. Why did you print it in that orientation? It looks as though it would become tippy when the printer is laying down the top layers.My new printer is performing very well!
