<p>The fixture has planar elements arranged parallel to each other and rotatably connected with a ball as a rotational axis according to milling slope. The ball with arbitrary diameter and the planar elements are made of a material e.g. glass, plastic, gold and silver. The planar elements have width greater than the diameter of the ball. Poles of the ball are provided with round, square or polyhedral leaves after connection of the elements, where the leaves have holes at its center. The ball is provided with pins at its poles, where the pins are bent based on use of the elements.</p> |
