Buttercup the Duck’s new foot is printed on a 3D printer and he walks & runs! (short version)

Buttercup is an amazing duck, hatched with a deformed left foot. This new design features a movable ankle with plastic springs for support, tread on the bottom for grip, and a new sock retainer on the back! This entire foot is printed on a 3D printer unlike his 1st prosthetic prototype which was made using a hybrid 3D printing/urethane molding process.
