Picatinny Rail Female Diamond Grip

thingiverse

Human is essentially the opposite of the previous smiley face :-) . To secure the rails, use a pair of M3 nuts and screws. I've found that printing works best when it's upside down, and support should be placed between the rails. Updated: Version 2 has screw holes farther apart, making it possible for both holes to align with the picatinny rail.
