CZ-3 was a CZ-series secretary droid that was twinned with fellow CZ unit CZ-1 in service to members of the Stacchati species. After a crash in the deserts of Tatooine the two droids became separated and CZ-3 ended up in the spaceport of Mos Eisley. In 0 BBY, CZ-3 wondered through the spaceport's streets past the local moisture farmer Luke Skywalker and the Jedi Obi-Wan Kenobi after the pair had sold an X-34 landspeeder to the Wioslea.
