$2 grip solution for any Oly (or similarly grip-challenged cam)

I knew about your "hack" before, and I was impressed then too, so it's well worth a re-post. I love stuff like that. I've tried to figure out a way to modify the sometimes fiddly FN1 button on my E-M5, inspired partly by you, but I haven't figured out quite what to use to make it more accessible. I've been thinking about sticking a small bead on it, or some sort of tiny metal clamp....
