The Universal Tool was designed to be used for everyday tasks for the astronauts. It can be a screwdriver, a fork, a hammer, anything! If the astronaut needs a specific screwdriver part, they can create it themselves and then print it out and attach it to the handle. Once they have used the part they can recycle it and use it to create another attachment. It is a never ending cycle that will help out astronauts for the future, because no one knows what is going to happen.
