MTG - Library/Graveyard/Exile Holder - Top

Looking at the library holder I already uploaded, I decided it has a lot of empty space, why not fill in that space and make it a lid?

Now you can carry your library around between the two of them, and when play starts the bottom piece becomes your library holder and the top becomes your graveyard holder.

Gave edges 1mm more clearance so it fits with bottom a little cleaner.
