# Why Machines That Bend Are Better
Procrastinating again... Anyway, this is cool. A series of mechanical devices (either 3D printed, or made of plastic/extruded) which have no hinges and typically a monopiece. Great mechanics and great engineering. I did not even knew such stuff existed.
@FailForward The guy said they can go over a million cycles before failing. That's kind of surprising and I wish he'd explained more - both about how they achieve that, knowing how many plastic tabs on things I've broken, and how they measure it (what's the probability that any individual specimen fails at half a million? a thousand?). Knowing more about the failure modes is essential to being able to use these things safely.
