Yesterday we got Chewbacca, and where would Chewie be without his bowcaster?
Today's build is a tool stand/depot/barrel. I'm not sure whether this is modeled off an actual stand as represented in any of the movies or literature, but I do know there are plenty of weapon and tool stands in the films, so it's not unlikely.
The crossbow is meant to be Chewbacca's bowcaster, which he uses in Episodes III, V, and VI. The other tools included are generic Lego, but they could be some of the tools Chewbacca used as he fixed the Millennium Falcon during Episode V. :o)
