Is it a bird? Is it a plane? It's SUPER THUMB!

Workers at a BMW plant in Germany have been given 3D-printed "super-thumbs" to reduce stress on their joints when they are assembling car parts. Each bespoke thermoplastic polyurethane thumb protector is created individually by measuring the worker's hand in a mobile scanner. It fits like a second skin over the worker's thumb, letting it move freely. But it becomes rigid when straightened, allowing the thumb to press down firmly but with less strain put on the joint. BMW said the use of the technology was part of its efforts to offer the "best possible support" to workers. I would welcome anything that is worker-focused, but this one tiny step, while by all accounts better than nothing, is probably only addressing one part of a complex problem. There are many things that can cause stress like this, including posture and the number of times you do a task. The obvious solution? More 3D printing. It's the only thing for it.
