Now here is a lovely story about technology and ingenuity:

My colleagues and I just 3D-printed a ratcheting socket wrench on the International Space Station by typing some commands on our computer in California.

We had overheard ISS Commander Barry Wilmore (who goes by “Butch”) mention over the radio that he needed one, so we designed one in CAD and sent it up to him faster than a rocket ever could have. This is the first time we’ve ever “emailed” hardware to space.

Details are fascinating. Worth reading in full.
