What devoted Whovian
would not want to own a full size replica of a Dalek
Eyestalk? Using some photos of Daleks (like the one in the fifth photo) as a guide, I used Autodesk Inventor
to create a 3D model of a Dalek Eyestalk, Autodesk 123D Make
to create a sliced model of the eyestalk, a laser cutter to cut the slices out of cardboard, and glue and a steel rod to assemble the parts and produce a model like images in this step.
I made this at TechShop
