as you're peering in to the hole, you should be able to see the faint outline of the bars, I sliced under the bars.. then slid the lid under the bars..

I have an idea. Could you use MS paint to draw a line where you made the cut to slide in the lid? It seems like a really good idea to put it in there behind the bars like you did. I just don't understand how you made a cut "under" the bars to get the lid in. Do you have any pictures of that step?
