Clarke’s 3rd Law and desktop fabrication

Arthur C. Clarke is an author famous for many things, including formulating a set of laws which includes “Any sufficiently advanced technology is indistinguishable from magic”.

At half-past midnight two nights ago, I saw a design for a 10mm spanner by Triffid Hunter on thingiverse. I have heaps of spanners, they symbolise something deeply “enabling”. You can build a motor with spanners. They are the machine-age equivalent of hammers.

I saw it, downloaded it, printed it, held it in my hand, used it on a bolt. In ten minutes.

Try convincing me that’s not magic!

It took me longer to photograph it and blog about it than build it.
