Abstract: A build material nozzle structure (202) comprises: an interface surface (208) to interface with a build material container outlet structure (100); and a retaining structure (210) to releasably hold the build material container outlet structure in an engagement position with the interface surface of the build material nozzle structure; wherein the retaining structure comprises one or more retaining elements (210-1, 210-2, 210-3) disposed in the build material nozzle structure to exert an attractive magnetic biasing force on the build material outlet structure to releasably hold the build material container outlet structure in the engagement position with the interface surface of the build material nozzle structure.
