摘要

The base (1) is designed in a horseshoe shape and has a small watertight compartment (2) for a data containing chip at the back. It is open at the bottom for an easy removal of the model and provided with vertical grooves (4) and triangular recesses (5) at the outer surface. An inner segment is connected to the outer segment with a bridge (7), slightly higher than the base (1) in order to be easily broken for a removal of the model.
