Originally this was built up from scratch using various small pieces of plastic assembled in layers. For the finished piece I made a mold and cast it in resin, but the molded pieces ended up needing a lot more cleanup than I had hoped for and never made any more than just the one. The light is a frosted piece of plastic over a couple of small flat LEDs and the bettery is behind the yellow button with a spring in-between it and the electical contact. Also you can see that orignially I had thought that the grey primer color would be best, but the graphite metallic color we found later seemed to match more of the scenes from the movie a little better.
