Can't have a space station without a robotic arm to help build the place, or to move things around. This is a key piece of equipment for any space station. Don't leave your planet without one today. 1/1000 Scale. Sadly this is way thin. Almost too thin. So we put up a larger version. Same length, just larger around. I have been assured this does print without issue. So in case someone wants this much smaller version. Just beware that this is less than 1mm, it's extremely thin. This model pushes the very limits of what ShapeWays "CAN" print. Also know that ShapeWays keeps losing this post production. But it does print and it is absolutely beautiful piece. This makes a great addition item to the Repair Dock Station. Almost no markup has ever been applied to this model.
