3D Printed Toy Watch with Mechanical Iris
摘要
The paper describes toy watch with mechanical iris. The motion of the outer ring counterclockwise uniformly rotates the five petals about each of their pivots. That reveals tiny secret compartment in the watch and, with child’s imagination, allows the power magic beams to spread out. For children, mechanical flower, imbedded in watch, is mesmerizing by itself. For adults looking for explanations, kinematic analysis of iris mechanism is presented.
