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. After getting our test prints of the smaller version of this arm. We figured out it is a bit too small. ShapeWays has not said there were any printing issues. But it's so thin that we felt getting this slightly larger version up was only smart. This is 1/1000 scale and makes great addition item to the Repair Dock Station. Markup has been dropped on this model.
