I have this sonic screwdriver of Eleven’s:
that also so happens to be a pen:
so it’s a little shorter (and a little modified) than a normal sonic screwdriver. So I’m making my own.
As you can see, I haven’t got far: I’ve just been able to finish the shape of the black rubber bit.
It’s made from rolled paper, as the rest of the screwdriver will (eventually) be. That does make getting shapes right difficult, and I was mulling over how to do this for a while, which put off me actually starting it a bit. At least it’s started, so now I have no excuse for not finishing.
