SummaryI wanted to make the NASA Wrench both tighten and loosen a bolt so I modified to have a socket mount on both sides. I made the socket mount an insert so if it breaks, you can easily replace it. You could also create different inserts for smaller sockets. See me build this on a Da Vinci Jr. on my YouTube Channel: https://youtu.be/mVOjwYw9jt8InstructionsI imported the NASA Wrench .stl file into Tinkercad and then removed the socket mount by running a square hole through the center. Then I created an insert to replace the socket mount. I included two of the inserts so I had a spare in-case it broke.
