3D wooden model kit from Wooden City with 185 parts to build a kinetic picture. With this beautiful wooden model kit, you can assemble a kinetic picture. A key is used to wind the integrated winding motor with rubber bands. The moving picture is started via a lever, which also allows you to adjust the rotation speed. The picture looks best when hung on the wall with the included hook, allowing you to enjoy the optical illusion of the rotations. The winding motor operates for about one minute. All Wooden.City model components are delivered packaged in a beautiful wooden box. Recommended age: 14 years and up. Number of parts: 185. Model size: 34 x 22.4 x 6.2 cm. Assembly time: approximately 6 hours. Easy assembly without glue (a small pliers and cutter/utility knife are recommended). Contents: Sanded plywood, rubber bands, wax, wooden axles (toothpicks), and a step-by-step building instruction with pictures. This kit is characterized by natural materials that can be assembled without glue. All components are already laser-cut and ready for assembly after being removed from the sanded plywood sheet. The detailed step-by-step instructions with images make assembling this wooden model very easy. Please note: Assembly requires some craftsmanship, as the delicate components must occasionally be joined with controlled force. If handled too carelessly or roughly, individual parts may be irreparably damaged. As with other model building parts, the rule is: "Carefully examine the assembly instructions, use less force, be patient, and proceed precisely." Manufacturer's notes: Wooden City is a Polish manufacturer of wooden model kits made from ecological materials such as birch wood, rubber, or wax. The sophisticated designs and production take place in their own factory.
