Examples of the present disclosure relate to a container for a three-dimensional printing system. The container has a chamber for storing a build material. The container has a base mounted within an open end of the chamber, the base having a channel structure and having at least one material-conveying structure. The chamber has an inner surface having helical raised portions to convey build material between the chamber and the at least one material-conveying structure during rotation. The at least one material-conveying structure has a radially aligned opening to receive build material conveyed by the helical raised portions in a direction perpendicular to an axis of rotation and is configured to transport the build material towards an opening of the channel structure.
