Abstract: According to one example, there is provided an accessory for a three-dimensional (3D) printer. The accessory comprises an upper structure to connect to a 3D printer build unit, the build unit defining a build chamber and having a movable support platform, the upper structure defining a build chamber smaller than the build chamber of the build unit, the upper structure being connectable to the build unit such that the accessory build chamber becomes the usable build chamber of the build unit, and an accessory support platform movable within the accessory build chamber, the accessory support platform having a base portion extending below the accessory build chamber to connect to the build unit support platform, such that movement of the build unit support platform causes corresponding movement of the accessory support platform.
