Fallout Power Armor Bobblehead

If you saw the power armor in the Fallout TV show and immediately thought, "bobblehead", this is for you.

There are so many uploads of the source model that I don't have a clear attribution, but thanks to whoever it was who saw fit to do the original scan.

The head and base have 10mm-cube-shaped cutouts to hold the ends of whatever spring mechanism you choose to install. I found a spring about 30mm long from a pump dispenser bottle and shimmed it with strips of paper that I cut from a business card. I've tried a printed plastic spring, but it's less satisfactory.

Does it bobble? More or less!
