# 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.
BTW, the whole channel of this guy is full of great stuff. Again and again I am amazed why I never heard of such amazing things before. There's so much interesting stuff out there...
