1. A method of making a 3-dimensional object that fits to a 3-dimensional object to be fitted comprising: a. a method of creating a 3-dimensional geometry model comprising imaging said 3-dimensional object to be fitted with an imaging device; and b. a method of transforming said 3-dimensional geometry model into said 3-dimensional object with a transforming device; c. wherein said transforming device is structured and arranged to select said 3-dimensional object conforming to negative shape of said 3-dimensional object or conforming to positive shape of said 3-dimensional object; d. whereby said 3-dimensional object custom fits with said 3-dimensional object to be fitted.
