This was a 3D print I could not pass up. Portal is a big favorite of mine and this model is really well done. I did modify the claw arms to attach with screws at the hinges to be a bit more robust. Chopped up an old audio extension cable for the wires and used plastic from a clear soda bottle for the outer cylinder. I decided it needed a proper display stand after I made it, so I grabbed some references from the games and modeled and printed my own version of the in-game stand to display it on.
