Humidor help

Hows it going everyone

So my neighbor gave me a pretty nice humidor last night. Its a 4 draw humidor, But one of the faces on the draws fell off, an he doesnt have it. So the drawer can still open. But it wont seal properly. I dont want to season it yet because i know all the humidity wont hold.
Whats a good way to temporarely fix this?
I dont want to hot glue anything unless itd help or be wise too.
Could i cut some wood and seal it an screw it in place?

Ill post some pics later today. So everyone can have a better understanding of what im teying to explain.

Thanks

Don't post anymore in this thread. It's a duplicate of an accessories thread that was erroneously placed in the "business help & advice" forum.
