NASA Makes 3-D Printed Wrench Model Available
First time accepted submitter smsiebe writes You can now download a piece of history by getting the designs for the wrench that NASA recently emailed to astronauts on the ISS. The wrench took four hours to complete and was the first "uplink tool" printed in space. You can check out a number of models and images on NASA's 3D Resources site.
The actual design of the wrench is fantastic; it has two moving parts that are printed inside the grip, so it comes out of the printer fully assembled and ready to be used (or not used).
