This IS the 21st Century. I don’t recall ever reading a sci-fi story where a tool was emailed into space. This is an example of real life getting very close to matching the concept of a replicator from Star Trek.
Made In Space, the California company that designed the 3D printer aboard the ISS, overheard Wilmore mentioning the need for a ratcheting socket wrench and decided to create one. Previously, if an astronaut needed a specific tool it would have to be flown up on the next mission to the ISS, which could take months.
