The Sonic Screwdriver ins based on the fictional device featured in the Doctor Who series. In particular, this version is based on the 9th and 10th Doctor's (Tennant/Smith). Using a combination of official photos and unofficial sketches, this sonic matches the visual proportions and scale of the television prop, including the base extension of the sonic's head, by pushing a slider on the side. The sonic has been designed in 8 parts, which thread and slider together to create the final product. Given the detailed nature of the design and the precision of the parts, a resin (DLP/MLA) printer is the best placed to print most of the parts. A precisely calibrated FDM printer may work for most of the parts, but the smaller parts may require some careful orientation and tweaks on an FDM.
The sonic has been designed to allow for the addition of wires and electrics, should you wish to add a some wires, a battery and perhaps a small LED. I have not specifics on how to do this, but I just tried to leave space for those who might want to take this to the next level.
No gluing, just screw most of it together using the printed parts, in the listed order. It should be easy to print and easy to assemble, using one material or several to customize the look and style.
