[Martin]’s design leverages the slot and tab connection we’re used to seeing in laser-cut boxes, but adds a living flex-hinge to curve each piece of plywood into a U-shape. The two pieces are ...

In this work, we manufacture living hinges of arbitrary cross sections from nitinol using a femtosecond laser micromachining process. We first determined the laser cutting parameters, 4.1Jcm -2 ...

The whole video is worth a watch, but he shows off the experimental design at the 7:47 mark. The hinge can swing normally but when positioned just right, the squared-off pin within slots into a ...
