Battery eject lever broken/replacement.

Hello I have the TX30 and recently attempted to switch my battery with a freshly charged one but when I moved the little blue plastic battery eject lever, it simply broke off in my hand with little to no effort. Can you please tell me where I can find a replacement part for this? I can fix it myself but I am having difficulty finding the part. Also, I may be interested in replacing the entire housing, regardless of available color. Please, let me know.
