Found this in my box of desk trinkets, and thought to share.
From what I remember, my father was given this demo print at some tech show in mid-2000s. I am not sure of the material used for it.

I still remember seeing 3D printers for the first time in a video, probably 20 years ago. It was sintered metal like this. It was a printer made for astronauts. They printed a crescent wrench and I was completely blown away. Little did I know that would consume my life as an adult…
