摘要

The base is made from a number of layers of sheet material that are cut out automatically, e.g. by laser or water jet, and stacked and joined together by nuts and bolts (1) inserted through holes (3). Rollers can be incorporated in the base for ease of movement, and an elongated slot (2) allows it to be screwed to the floor.
