What can i do with this?

My old 5mW laser very old and broke, i tore it apart and tried to get the diode/module out but broke the entire thing. I didnt care too much the whole inside of it was corroded. All i have left is the thing where you put the batterys, the tailcap. Should i toss it out or what.

Toss it. Keeping it as a replacement part is a waste of space because something that simple will never fail.
