3D Model of a New Series Dalek. It is untextured, but materials separate clear parts from everything else. Credit to projectdalek.com for the plans, to make sure this is completely to scale. Ngons are used, but normals and bevelled edges mean that this doesn't effect the shading. While this is not rigged, each part of the Dalek is a separate object, and the origins are set to the pivot points.
