Magic The Gathering 60 card deck box that slots together and looks like a library and a graveyard when taken apart.

On the library, I added some windows to the sides and extended them up so that the cards wouldn't fall out the side.

For the graveyard I made the sides a little thicker so they would be more durable, as well as changed the design of the fence to be easier to print.

For both sides I made the floors solid as I was having trouble with the box flexing a lot when they were see through. It should be a pretty good friction fit on both halves, but I have been putting a rubber band around it just incase.
