A custom-made cosmetic component of an external upper or lower limb prosthesis designed to provide an aesthetic outer shape and surface to the prosthesis via one of various forms (e.g., foot shell, filler, skin, stocking, glove, limb cover) produced for a specific patient manually, or using computer-based anatomical imaging 3-D printing. It may be made of various materials (e.g., foam, thermoplast, wood, silicone, fibreglass, resin, carbon fibre), and may additionally be designed to protect the prosthesis from external agents (e.g., debris, water splashes, impact forces).
