A device that goes Ding! when there's stuff! Perfect for tracking down Zygons or cooking eggs.
Miniature prop replica scaled to 1/6 scale- could be scaled up for a larger replica.
Due to the small nature of this model I used a mult-jet fusion printer to manufacture mine (Shapeways) in order to capture all of the details, however a modern resin printer could easily print these now with no issue.
