    The springs (in red) (WIP_Spring.stl)

    are to hold the tabs (in blue) (Release.stl) straight out to lock it in place.

    They need to be stiffer. The problem is the small space to compress them in. If I add more curves, it won't compress enough. If I just make it thicker, it won't spring back like it should (it bends the plastic). They don't have to be the same style or anything. They just have to work. I don't care if it takes a complete redesign either. Any ideas would be helpful. Even if you think your idea might not work, it might spark another idea or a different way of looking at it. Metal springs are another option, but I would need to know what type and how to implement it.

    My original design only had one long spring that went from top to bottom. But moving the gear / knob closer to the middle made this not an option.

    I wonder if having the spring off center would cause any issues. Thoughts??

    Perhaps these properly scaled?

    Nope, sorry. Not strong enough.

    Simple, dump the spring and put in a catch.

    Make the simple pinch operation into a hold (something) and pinch.
    This makes it passive and simply moves to a position where it interferes with the pinch operation.
    Think safety-toggles on lighters.

    Not really sure what you mean. Can you give another example? Maybe a picture or something?

    Let something pop in the way of actuating the pinch handles.
    User needs to push a putting to release the something you let spring in the way.
    Typical solution is a lightly sprung slider/plunger.
    When pushed, the thing that was in the way is now out of the way.

    A key lock! ...with only 2 tumblers.

    ...in this sample, when you push the button (red circle), the trigger is allowed to be compressed.
    The button is spring loaded so once the trigger is released, the button is restored to it's safety position.
