Batman Signal Stencil

One of my kids wanted the Bat Signal on his birthday cake, so I made this. Printing it in gold PLA, layer of plastic wrap under it if I'm feeling particularly twitchy about the not-rated-for-food-contact plastic issues at the moment (might just only put it on briefly and accept the minimal exposure), using either dark chocolate or blueberry as a topping to make "night sky" effect. Print size on this is just under 4in diameter (limitations of my printer). Would also work as a stencil for drawing
