These Are the Droids You're Looking for

Even to the casual observer, the real hero of Star Wars can be a matter of debate. While Luke Skywalker's heroics in his X-wing starfighter sealed the Rebellion's victory, he would not have a target to destroy were it not for a certain short, round, sassy astromech droid who faithfully carried the plans from Princess Leia.... well, you know the story. The point being, R2-D2 is a fan favorite for many reasons, which is why many people feel inspired to build their own little buddy.
