Yeethammer More Ergonomic and Secure Foregrip

I found that I was holding the foregrip up high and the corner of the foregrip bracket was jutting into my hand, so I've smoothed that out.

In addition, I didn't like how the foregrip bar could move, so I've stuck a hole in so that you can run an M3 screw through to secure the foregrip bar in place.

Included is a file with a foregrip bar that has a hole in the right place already, I haven't tested this though as I just drilled through the existing bar I had printed and that works well enough.
