OP,
I've seen your prior posts and you seem pretty smart (unlike many other posters here and elsewhere online). Therefore, I firmly believe all you need to do is search on NH for "absolver" and look at the pictures of what people have done. There is no "trick" or special part to use. It's honestly as simple as figuring how to guide high pressure air from one opening into a 3 or 7 bundle of barrels.
I made my own set of absolver shells and couplers by going to a bigbox hardware store and looking at what PVC screw and friction fit couplers, pipes, tubes, and other doodads they had and just brainstormed internally for 15 minutes. I then bought a wide variety of sizes and shapes (they're so cheap) went to my workshop and just experimented with only hot glue, a saw, a mitre box, epoxy, PVC cement, an X-acto knife blade, and polystyrene card stock. Literally, that's all I did and was able to figure it out despite being one of the lowest IQ members on NH.
Here, look at what I did:

No, I don't have the part numbers or exact dimensions, but you don't need them if you go to a bigbox hardware store and just spend an extra $4.75 on PVC parts.
In hindsight, I would have used a screw couple with a larger opening, but that's the only thing I would have changed.
Based off of this, I likely will use this another time because I'm planning on using a 1/2 inch cpvc coupler, however, I will use your system. I know this would be a weird part if it exists, but does anyone know if there is a cpvc coupler PLUS a screw couple part? Like I'm saying a screw coupler of a certain size, then the inner diameter fitting cpvc through friction fit.
I GOT THIS ONE
You mentioned something about 3D printing, which I've done a bit with for absolvers. I made a simple 3 shot barrel in CAD, here it is:
Just stick a stub of 0.5" CPVC into the back to attach it to a coupler system.
Also here is a link to the .STL, if it doesn't work for some reason let me know:

Using this, printing this today, do you know if this is airtight already or should I just wrap it in tape so no air escapes?
I did it, just the way I had said it. All you have to do is fill the head with hot glue, add more stuff/hot glue to kill dead space in plunger tube, and cut down barrel/epoxy on 1/2" cpvc pipe and if you want a coupler, put on a coupler. Hits like a truck on steroids singled, went so fast using a stock dart that I couldn't see it.
Ok cool, the group consensus seems to be to use 1/2 inch cpvc, so that's likely what I will do, thank you
