The Guardian:

German car manufacturer BMW has turned to 3D printing to physically augment its car-plant workers, giving them stronger, augmented thumbs.

The 3D-printed apparel acts like support brackets for the workers’ thumbs, reducing strain and helping them to fit certain parts into the cars more easily.

Each “thumb” is created as a custom orthotic device using a portable 3D camera, which captures the unique size and shape of each line-worker’s thumb.

You need to look at the pictures to truly get this. Really cool use of 3D printing technology.
