Then some of you might notice that the bar for the lids hinge (shown in the attached picture) can slowly migrate then fall out. I bought one of these cases for a co-worker and they were too busy to notice and push the bar back into place. Of course, they tasked me to fix it. This bar does the trick. 1/8 fits just fine though you will have to cut it to size and make sure to file down the rough edge.
