Well, we did it. By means of modern technologies (involving lasers and magic), the backscratcher is once again among us. I’d like to thank ██ ████████ ██████ and ███████ for their efforts in obtaining three dimensional scans of the obelisk, Ms. Edith S. Buck of the SFML and her team for unearthing and restoring the antiquated schematics, and everyone involved for helping to scratch this itch.
If you want your own, you can order it here on Shapeways. I recommend the white plastic one. Sand, paint, repeat.
