Stripped screw, button arm moves; request and suggestions

[BZA]

Hi! I really like my Cyborg keypad, but I am having a big problem with it, something that has gotten me "killed" several times. Sometimes, when some part of a game is hectic, I press (or "pull") too hard on the buttons, and because the single screw that holds the whole index-finger button-arm in place is stripped, the arm moves (a lot), and I hit the wrong buttons, or I don't hit the right ones fast enough, and this is probably a dangerous situation, so I probably die.

I realize that, ultimately, a big part of this is user error, but maybe you can improve the idiot-proofing.

Suggestion 1: When designing the next model, look into making the screws harder to strip. It seems relatively easy to do in some cases (notably the screws on the "bottom"), and not in others. (I'm no engineer, but possibly it's harder when there's also a metal nut for the bolt.)

Suggestion 2: When designing the next model, consider adding another screw (so there are two) to "lock" each arm's rotation/etc. I think one screw isn't enough to secure such a big piece (and it's one of the only parts that's subjected to much force).

Request: Any ideas about how I can stop the index arm from moving, on the keypad I have now? (Super-glue is my best idea currently, but I suspect there are better.) I adjusted the angle/position of the arms so the index arm is already fully "back" and "to the right", so it can't rotate any farther in those directions, but I still pull it "toward me" sometimes.

Thanks!

Thank you for the suggestions.
Might be that the joints or pivot ball is worn out.
See if the joint doesn't have any cracks on it.

Angle the tower to the side and check the pivot ball, see on whether the groves are not ripped off and it still has a way to grip.

The joint has no cracks. Is there a reason to think that the problem might not be the "lock" screw?

For now, any better ideas for holding it in place? Two of the four towers move as if that screw is only partly tightened: some resistance to movement, but not enough to withstand medium pressure.

Try changing the screws, but I suspect it`s the joints. Do you have a 3d printer ? Could share the file for them to test a new one

My mistake, I said "'lock' screw", but I meant the whole tower rotation lock mechanism; you are correct that the actual damaged part is probably the 3d-printed clamp piece that keeps the joint still, and not the metal screw, or the ball joint itself. But no, I don't have a 3d printer. It seems like super-glue may be my best option for stabilizing some of the towers.

Update/edit: I did that, and it's ugly—I wanted to put glue on the "sides" of the tower bases, and it dried white—but it works.
