M-LOK Compatible K-Grip Foregrip

It's an MP5 style K-Grip! The original author provided two additional files - the short and the long locking tab. These press into place, and should probably be glued. I've printed a few of these now using carbon fiber filament, and they work good and function great!

This specific version has been modified slightly on the geometry to reduce the sharp edges that carbon fiber filament leaves, and has also been modified to accept flat head screws.

I tested durability on a knock off M-LOK rail I had kicking around in my parts bin, and I actually bent the rail before breaking the grip, so this guy is good to go with the proper print settings! I would avoid PLA if possible, but unless you're doing mag dumps you're likely to be fine.

I have updated some of the geometry of the K-Grip compared to the original to make it more comfortable when printed in carbon fiber filament, and additionally modified the screw holes to allow the use of button-head flat screws as opposed to the original counter-sunk ones.
