I have made 2 versions of the 9th/10th Doctor Sonic Screwdriver for 3D printing. One is a first season, non-extending, stunt prop. The other is in pieces so it does extend. Are you looking for STL files like the 3D printers use? They were not designed with cavities for electronics. I plan to do that, I just haven't found the time. PM me if your interested. I have a thread with pictures on the forum.
