Final version of battery holder after many trials and errors.

Yasojima presented a comprehensive design and production proposal according to the medical device manufacturer’s needs. The battery holder was 3D printed with design changes to improve usability, safety, and durability. The parts that combined to form the body of the driver required precision machining. Because only a small number of devices were required to be produced, Yasojima was able to significantly reduce lead time by eliminating the need to create molds or drawings and working with CAD data only.
