- "This is a repair part for a B3. Whatever happened here, it's recent."
- ―Quinlan Vos
B3s were droids used by the Confederacy of Independent Systems during the Clone Wars. At one point, some were stationed near a listening post on the planet Vanqor. A curved piece of metal used in B3 repair was uncovered by Quinlan Vos when he and a Republic strike team attacked the listening post.
