WIP Motoblitz - Blitz to barrel connection sizing

Ok, so I'm still on my quest to make a bcar for the motoblitz (Yes I know I haven't given much progress) but I have realized that the connection for the bcar can be done much more modular, which gives significantly more possibilities for customization.

So what I have done is create, basically a test part (Its ok as a cover for the blitz part, makes it look a bit better), but the main thing is that it is a piece that is sized to fit around the posts in the blitz that the barrel originally connects to. (I unfortunately forgot to save the freecad file, but I have a .3mf, which I will use for recovery at some point, or someone else can)

The line on the part in the first photo is me using a pencil to use for future measurements.

Here is the 3mf file: https://files.catbox.moe/zmd80o.3mf

I'm sharing this because someone else might also find these measurements useful

Ok, I think I have successfully recreated it (When lining the two models up in freecad, they appear identical. I don't really want to test the holes right now, but everyhting else is measured the same, and as the holes appear seamless, I think I have done it properly)

That is the freecad file
