I have created a replica of a Sonic Screwdriver, and oh my, it (almost) works. See Sonic Screwdriver ...demo video below. The original was used by the Tenth Doctor Who, David Tennant, who played in the series from 2005 until 2010. It was my entry to the cosplay design contest.
Elaborate instructions on what's needed, how to print and how to assemble is included in the pdf manual. As I didn't have silver coloured filament and transparant blue, I had to improvise somewhat as is being described in the instruction. Naturally you can avoid the painting and fiddling by just ordering the right coloured PLA. The flashing LEDs are created using a bicycle light. I have added a picture of the version I used. Depending on your version you might need the 2 battery pack or the 4 battery pack.
The box has been printed using ColorFabb Woodfill. Two versions are uploaded. I have used the 2 mm version in combination with a paperclip for the hinges. You can also use the three mm version in combination with a piece of filament to create the hinge.
