The "Yes You Can" prosthetic terminal device boasts a minimalistic and neutral design inspired by real hand shapes, ensuring it's suitable for daily use regardless of gender. Its anthropomorphic appearance allows it to blend seamlessly into any occasion - be it everyday tasks or festive events. The design's universality is further enhanced by its adherence to the Scandinavian tradition in product design, which emphasizes both functionality and aesthetics. This timeless concept ensures that the device can assist disabled individuals across cultures. Technically, the "Yes You Can" terminal hand is a voluntarily close (VO) type, drawing inspiration from the K1-hand developed by Evan Kuester. The device is body powered, with finger flexion achieved through shoulder abduction, which pulls a wire connected to strings running within the hand's built-in tracts. Finger extension occurs automatically due to rubber bands placed in pipelines on the hand's backside. To connect finger parts with hinges, use 3D filaments (1.75 or 2.0 mm diameter), glue, or melted material. Alternatively, opt for a nylon stick or screws. For optimal printing quality, print finger components with 50-100 micron layers and 100% fill, while the palm can use less fill (e.g., 70%).
