The device has a band provided with active and passive sides (2a, 2b), and a three-dimensional carving (3) formed on the active side. The carving defines hollow zone with respect to one of a set of projecting zones, each having a flattened top that provides an extension plate. The extension plate is parallel to a passive side (2b) of a band (2), and channels cross each projecting zone of the plate at the passive side. An independent claim is also included for a method of obtaining a modeling device. |
