The Iron Giant Bolt

This is a replica Iron Giant bolt that I designed to be printed and generate the last scene from iron giant where the bolt comes to life, flashes and beeps and returns to the Iron Giant.
The parts are easily 3D printable and uses some simple electronics for making the sound and lights flash and a few M3 bolts.
Some soldering skills will be required to complete or just print it as a static prop.
I used an arduino Nano, old Chrismas lights 5mm LEDs, a small switch and an old toy speaker. A 9Volt battery powers the arduino and flashes the light and beeps.. it's not annoying at all and we made a game out of hiding the bolt around the house until someone heard it and then found it and hid it for the next person.
Have a read of the Instruction PDF and hope you enjoy it.
