UPDATE: I uploaded two new files that are now solid, they no longer have the seem down the middle.
Bookcase for Gloomhaven. Occupies 2 hexes. Since obstacles do not block line of sight in the game I assumed they where below shoulder height for the human scoundrel.
Made from dutchmogul's awesome Delving Decor: Wizard's Shelf
4x (2 hex) Bookcase
