3D-Printed Portal Companion Cube Puzzle Box
Animator Joaquin Baldwin made this Portal-inspired Companion Cube puzzle box using the Shapeways 3D-printing service. Its sides slide away to reveal two more cubes, and the panels have Aperture logos on their interior. The amount of etched detail on each panel is impressive and the print looks very sturdy. Due to its complexity and required assembly, Baldwin isn't selling the puzzle box, but you can buy his other Shapeways-printed designs here.
