This Portal Turret is a red-laser-shooting robot from the video game Portal.
The parts were modeled in AutoDesk Maya from scratch and then a Maya MEL script was used to convert the parts to separate STL files. The STL files could then be printed on a Cube 3D Printer.
The reference picture was used to approximate the shapes of the parts. The parts included the two halves of the body, the two side bends, the back bend, the three leg caps, and the three legs. To simplify the process, all three legs are the same length.
