Stop. It's the claw!
I didn't see the point in printing a bunch of flat parts for the RobotGeek 9G servo gripper but I really liked the design so I re-modelled the parts in Sketchup, stretched the fingers out getting rid of many support pieces and merged the plates into a single piece.
I also re-aligned the holes because I felt they were far too close together for the gripper gears to have the correct spacing between their teeth. I used M3 screws for everything, just use your best judgement and whatever is easiest - I just happened to have M3x15mm and M3x25mm lying around.
The back of the gripper has also been modified to be a drop in replacement for the MeArm's weak claw which can't even lift bro. One issue is that this gripper is a lot heavier than the standard one and its centre of gravity is much further forward which does necessitate having good servos in the rest of the arm.
