I was doing a shell swap for my NDS Lite and everything went smooth until I tried to lay this little black door back down on the ribbon. It popped off and then I tried to put it back on and it snapped in half. It's so damn small.

I was wondering if there might be an alternative to buying another motherboard for $50. It would be a real waste if the new one just did the same thing anyhow. I need some ideas, anyone?
I tried a few kinds of tape, but it's a real pain trying to get it to hold the ribbon down just right, it just isn't going to work. Maybe a paperclip or something, if that won't hurt anything. I don't know.

I circled the small door in red, in case you don't know which one I'm talking about.
Thank you in advance.
