PsychoBob recently completed part two of his sculpture of Atlas from Portal 2, with an entirely 3D printed ‘big red button’ base upon which Atlas rests, and an embedded LED circuit powered over USB. His steps are thoroughly detailed over on his blog:

Assembling the ring, the corners and the wooden base were easy and straight forward (block 1). Atlas and the red button were not a problem either (block 2). Getting these 2 blocks connected together however, wasn’t so easy as the wires were too short so that I couldn’t have them side by side when soldering the 2 circuits together. So I grabbed 2 pint glasses, a ruler and suspended block 1 above block 2. This gave me enough room to solder everything together and then I assembled these 2 pieces to make the final project.
