Step 1: Start

What you need:
1) Two small batteries 3v
2) Three LEDs and resistors for them
3) switch
4) Package for raincot
5) Silver and black (acrylic) paints
6) Super glue
7) rasp (Sorry, i don't if i could name this tools like this. If you don't understand, this is translator's mistake)
8) cold welding

Step 2: Shape

Using rasp you should make relief like you saw in movie. After that make the simpliest LED lamp and cut off a hole for it in your basis

Step 3: Next

Cut off a track for your switch and put there the screw with a nut (second photo). Glue together your halfs, don't forget to add electronics ;)

Step 4: Final

Using cold welding make a button and glue on a nut as you see it in the picture. Paint your model

Thank you for your attention
Good luck!
