Does anyone make non standard iFit backs?

Further to my 'smaller bore inserts' question I'm wondering if anyone makes iFit compatible backs? I don't have a lathe to make my own so I've been trying to design a plain one on Fusion360 to outsource to PCBWay or JLCCNC and figured I'd ask on here to see if someone's doing them, of has done some, already.

Specifically, I'm after an old Angel thread version. I know TechT made an Angel back but it's the newer Angel threads. It's for one of my Angel 05 Speed builds so, as far as I know, it has to be the old Angel threads to pair with my Hammerhead barrel. I'm doing a similar setup for a couple of my Spyder builds, iFit to Armson, so I'd like to do the same for my 05 Speed.

Alternatively, it could be a custom freak back with old Angel threads on both ends. I have one with Cocker threads on both ends (currently on my pre-2k MiniCocker project). I'd bought it years ago, probably around 2012(ish), so I can't remember who made it. This wouldn't be ideal for the build as it would make for a very, very long barrel, but if it's all I can get then I'll adjust my plan/build to accommodate.

If there aren't any machinists on MCB willing to make either version...
Has anyone outsourced paintball parts to somewhere like PCBWay or JLCCNC? I've never used them so I've been looking at them, as mentioned at the beginning of the post, but I don't know how to do the required technical drawings. If anyone on here has experience of using these services, can you tell me what you had made and how complicated was it's design, how easy was the whole process, how good was the overall finish on the item, and are you happy with what you'd received? I don't like to bother a machinist (or people in general) unnecessarily so these companies seem like a good 'final option' for me if there aren't any machinists on MCB willing to make one.

I've heard of people getting barrels bored for TechT ifit inserts, however they would have to use the inserts backwards which defeats the entire purpose lol. The inserts are designed to go into the adapter from the front, then the barrel that gets screwed on holds the insert into place, the insert has a lip on the top.

I guess one method could be getting a barrel in a particular threads, old Angel for example, slicing off a section, bore for the TechT insert to sit correctly, thread the cut end for whatever barrel threads

Alrighty then. After a quick massage 'chat' with flyweightnate we've figured it's not really feasible to make an old Angel thread (M24x2mm BTW) iFit back. There's simply not enough material to make it work because of the OD of both the insert and the barrel. Here's a quick mock-up I did in Fusion360:



If I push the Angel barrel right down to the iFit insert then it would cut into the threads, which I'd extended all the way up in the hope that it'd add strength where it got a bit thin. This made me think of adding a spacer between the insert and the barrel but it's still a bit too thin. This leaves only one viable 'answer' so to speak. That's the 'Angel to Angel' Freak back, a freak back with M24x2mm for both external and internal threads. I was initially against adding too much length to my barrel setup but funnily, after measuring my Angel Freak back with my Hammerhead aligned to match the AA Freak Front, I'd only be adding an extra 1.5" to the Freak barrel setup I was using. Seeing that, I'm actually not sure why I was so against that idea in the first place. 🤣
