Early Prototypes

The hand brace was an early idea that did not get chosen after a design evaluation meeting with our TAs.

The 2nd iteration of the drawer was a big step in the right direction when it comes to the final product. It uses the pin and track mechanism that was in the final design, and was overall much better put together.

The final prototype is a refined version of the 2nd low-fidelity prototype, better executing on the materials selection and stability.

The initial drawer prototype was created using strings instead of the current pin and track mechanism to open and close it.
