Sword in the stone diorama with removable sword

It's the sword in the stone from the Arthurian legends, but instead of a regular stone it's in a cave. Inside the cave is standing a knight in full armor (supposed to be Arthur).

I'm not sure how well the sword will come in and out because I haven't printed this yet.
Knight is made to be glued into the cave.

Please post a make if you do end up printing this.
