Method of making customized devices and kit

A method of assembling a handheld, electromechanical device useful in mammalian body-care from a kit having interchangeable components comprising the steps of:

• a) selecting as a first component a one-piece housing having a single opening defined by a rim, wherein the rim circumscribes a rim area and the one-piece housing has a projected area that is substantially larger than the rim area;
• b) selecting as a second component a unitary insert dimensioned to be insertable through the opening defined by the rim, the unitary insert comprising a frame having disposed thereon electromechanical elements interconnected in an electrical circuit;
• c) inserting the selected unitary insert through the single opening of the housing;
• d) selecting as a third component a removable cover arranged and configured to cooperate with the selected unitary insert;
• e) removably applying the selected cover to close the opening of the housing;
• and
• f) attaching the unitary insert to at least one of the one-piece housing and the removable cover;
• wherein the kit comprises at least one of each of the first, second, and third components and a plurality of at least one of the components and wherein each of the first, second, and third components selected are arranged and configured to cooperate with the other selected components.
