re: Something thats slightly flexible might work, you'd have to test it. depends on a lot of factors like infill etc. If you want real flexibility you ...

hey :) as @joppedc mentioned, PLA might break easily. I would try PETG, it has some flexibility depending on thickness and infill, but it's still strong enough to use for something like that.

Nice! thanks!

Is there some reference online that would give some flexibility/strongness measurement of these 3D printing materials based on the thickness/infill?

I don't know about such a reference, but something like this might help get a better comparison between materials:
