I agree. Super glue does not work well with any flexing. I would use a mechanical fastener. But cutting the whole thing out of silicone rubber would allow for flexing of fingers. The design would need to consider what you are trying to move with the fingers. How much do you need them to flex??

Our redesign of the AM stars was intended to make the fingers stronger for our intake. This was for the flat frisbees. We experimented with several heights and positions until we found one that worked.

If you were using these with something that moved easier (balls) you could get away with more flexible fingers. The frisbees did not want to slide very well and caught on the thin plate we used in the front of the collector. We ended up using a thin polycarbonate sheet in front of the aluminum plate and that worked well for pick up
