Cello Prosthetic
A custom designed 3D printed prosthetic meant to allow a middle schooler without a lower arm and wrist to play the cello. This prosthetic replaces a conventionally manufactured prosthetic that was heavy, too short, and lacked the necessary attachments.
Features

Designed adaptors for the client’s current arm as well as a custom one designed by a colleague. These adaptors incorporate angle corrections in 3 axis to provide the most comfortable and technically correct bow position.
A bow clamp specifically designed to fit the shape of a standard cello bow. Tolerances had to be designed to deal with slight variations in bow shape, but be tight enough to ensure that pressure was applied evenly to the bow to clamp it.
New model of the prosthetic in the works with a dynamic wrist joint attached to a linkage to create a parallel bar mechanism that keeps the bow level at all angles.
