How can I enlargen the fins and ribcage of the fish below? I need to 3D print the model but currently at the moment the peices are too small to print or they snap off after being printed!!!I just need to make them thicker so that this wont happen.

You might use Displace modifier with vertex group to enlarge the delicate part.
