Remixed from my original model, which uses 2 screws and was quite a hassle to assemble. That's the one in the picture, but they look the same. Now, the only hardware it needs is one M3 by either 8 or 12mm Allen head machine screw for underneath the grip (or anything that fits).
Print in the same orientation/settings as the original files. None of the pieces need supports, however, the grip piece would benefit from a brim.
There are a few built-in supports under the grip however, remove those with pliers.
For assembly, screw on the grip as normal, then install trigger guard and slide on the labelled "Battle Axe" part, I think it's called "Grip To Body Chunk" in Sillybutts' files. Lock the modified trigger guard into place like normal, you might have to wedge it a little, hopefully not. Then take the screw and screw it :) up into the bottom of the grip to lock the guard in place underneath.
Names of the Knuckle Guard files refer to the pattern/texture on the front face. If there's any more patterns you'd like, let me know in the comments and I'll see what I can do, although it might take a few days for me to get around to it since I'm still a freshmen in high school, I'll do my best :)
Stay tacti-cool! (homage to Coop)
