This prosthetic hand was scaled to fit the size parameters of a 3 year old. There were many complications with creating such an intricate design. A big take-away lesson was that not everything needs to utilize 3D parts. Only parts that would be able to be produced in a cost efficient way should be 3D printed.
This hand will be donated to the e-NABLE organization, which matches 3d printed prosthetics with children. If this hand is accepted, the design will continue to be used to produce 3D printed prosthetics for the organization. Read more about e-NABLE at enablingthefuture.org.
