Designer relates to the field of children's creativity, namely for games that allow you to gather spatial and three-dimensional figures of varying difficulty. The objective of the claimed utility model is to provide a designer with more reliable fastening between the parts. Take the first part 1 and a seat 2 of the connector 3 mounted projection another detail of the bottom 1. As the groove 4 has a rectangular recess, the connector 3 has a protrusion, for example, a circular shape, the area equal to the area of the upper slot 5 and the rod 6 to the width of the connector equal to the width of the groove bottom 4, the rod 6 with the protrusion of the connector of the connector 3 enters the upper groove 5 perpendicularly through the bottom groove and a groove 4 in the form of through holes 7. Once through the top groove 5 has come protrusion of the connector 3, the connector pin 6 razvorachi in ag ood sort line to the first part 1. After pressing the protrusion of the connector 3, the fixing rod 6 in the lower connector recess 4 and the connector 3 in the upper protrusion forming a single recess 5. The flat design, which can be closed in a circle, wherein effected rigid mutual fixation of parts each other, imperceptible by visual inspection. In the second embodiment, the groove in the form of a through hole 7 and lower groove 4 have a cruciform shape, so that the fixation rod connector 6 in the bottom recess 4 is possible in all four directions.
