These parts have been 3D printed on a MakerBot Replicator 5th Generation. They will provide the basic armatures for animated characters which will be seen from the waist up, sitting at a table, doing party tricks. The basic modibot files have been adapted with a disc added to the hips (highlighted in yellow on the screenshot) to provide a stable base which can be taped, Blu tacked or screwed down. The armature has been scaled up to 240% to create a character with a nominal standing height of 30 cm/12 inches.
