Inspired by some similar designs, I designed a pair of customizable bracelets. They get their flexibility from their many folds. Even printed in relatively brittle PLA (the brown material), the small amount of flex that can be coaxed out of each kink adds up to make the whole thing pretty elastic. The blue material is a PLA/PHA compound that is even more flexible and durable.
