Description:
We are developing a new protein shaker bottle called Twystr. It is a modern take on the supplement mixing method. Unlike traditional shakers, Twystr features a built-in container that holds dry powder (e.g. protein) separately and releases it as a liquid via a twist or other mechanism.

This contest will select the best bottle design concept and CAD model based on form, function, and creativity.
