Ill take 4 thanks!

What size is the complete horn? Is this for yourself or are you considering to go into production?

The outer dimensions of the horn are 477mm x 336mm x 203mm.

This is just for myself, to keep myself busy. An integrated version of the SmallSyns speaker, with a little bigger waveguide (roughly like a SEOS19.5, but with with 90x65 coverage angles), using the same drivers even. It has to be done in halves, to get it to fit the printer capabilities (which is 300mmx300mx400mm). I doubt that production of this horn would be feasible, as each half of the horn takes 13.5 hours to print. It's not a fast process! Kind of fascinating to watch the printer do something like this, though, waste a lot of time just watching it!

Nice work! Looking good so far! Is it PLA?

Yeah, PLA, at least for now. I'm very new to 3d printing, so PLA seemed simplest. I played a bit with PETG, but it's more expensive and seems to have more issues with stringiness and warping when it cools.

I'm also new to 3D CAD design, there are a couple of issues with the design (nothing I can't fix with a filament pen, though, some holes and gaps.). I have to print the other half still to see whether I have the synergy midrange volumes and ports close.

Yeah, I kind of noticed that. My wife did, too. I blame you, you got me started on this.

How long did that job take? The killer is a filament tangle 90% into a 12hr job. Arrghhh!

Nice. Every mans' dream (at least on this Forum) - a one piece one print synergy.

It's 13.5 hours for each half....27 hours per horn! I could probably speed it up some, but didn't want to risk that at this point. Fortunately the first one went through without any drama. The second half is printing now, but it got tangled about an hour into it, I had to restart (after hacking together a quick filament guide to avoid the same happening again). Fingers crossed, maybe I'll have two halves to test tomorrow.
