I need to do this also among other issues I have with the console. Its a cardboard so I think the fix is something like how we fix the plastic bumper eye lid issue with metal on the underside. Personally It would be cleaner to buy a quart of fiberglass resin and coat the underside with it. That would hold its shape for sure. I may remake the entire console out of fiberglass due to many contact points on the cardboard where the metal cross brackets have worked their way loose. This is a good thread
