M7 Bayonet, M8A1 compatible, larger tang, with screws.

I took's MsFormula's resized M7 bayonet (https://www.thingiverse.com/thing:7256637) which is a remix of another thing and added the screws in the hilt that the real M7 has, made small pins for the rifle mount retaining mechanism, and slightly made the blade smaller as the original design was still a bit too large. I lengthened and widened the tang of the blade as it tended to fall out for me with my crappy glue. I'd recommend both gluing and screwing in the blade and screws, as 3D printed screws are more just for the looks and I don't trust them. Also removed the markings on the blade, as they aren't actually there on the real thing. Just glue it all.

The handle file is the handle and nothing else.
Guard is the blade's guard and the barrel mount.
Blade with guard is how the real thing is made, the guard and blade as one piece. I'd advise you print this instead.
"Small parts" and all that is the screws, nuts, bayonet latch unlocker things, and the pins for said things and the bayonet latch. The large one with a small and large section is the one for the larger latch, and the smaller ones are for the unlocker things.
The latch is the bayonet latch thing.
And the last file is self explanatory.

Not tested, not printed, and my first model, so beware.
