OT: Living in the future: 3D printing edition......

Today I was working in my office, in a project involving Torx security
screws. I'd bought a set of bits (delivered overnight by Amazon), but
found that I did not have a 6mm driver handle to use them in.
But in the next room sat one of my 3D printers. I downloaded an STL
file from the net, and 18 minutes later had my handle and
could continue the project.
I feel a childish sense of delight in this. It's a bit like owning a
Star Trek replicator. I conjured this tool out of the ether and into
actual existence.
