Butterfly Mechanical Wooden Model kit by Ugears This 3D puzzle for self assembling creates a beautiful Butterfly model. The Butterfly is not a static stand model, but an animated kinetic sculpture. Each of its details designed to make sure it fits its own place and plays its own part in the workings of this outstanding mechanism. Equipped with a rubber-band motor, the mechanical automaton moves imitating the flutter of a butterfly with no external power source or batteries.Technical Characteristics: Number of parts: 168Model Size: 14.2 x 22.8 x 11.4 inPackage size: 14.6 x 6.7 x 1.1 inMade of sustainably sourced high grade woodTop-notch quality: a laser method is used for cutting items from a plywood board that provides precise hairline cuts The details have to be pulled out of the boards and assembled to create a complete modelDoes not require glue nor special tools to be fully assembled into a functional modelComes with step-by-step, full-color, easy to follow instructionsLevel: IntermediateAssembly Time: 3 hoursRecommended Age: 14+Kit weight: 1.28 lbsManufacturer: UGearsMade in Ukraine How it works:The assembly is constructed by blocks: initially, the details must be put together to form smaller blocks that in their turn will compose the whole model. The process of assembly is described in a comprehensive step-by-step instruction manual with detailed color illustrations. The delicate wings of The Butterfly are made of craft paper. The lower wings change their tilt angle when the model is working to ensure that the movements of the automaton resemble those of a real butterfly. Two front pairs of its legs move while the wings flutter. The back pair of legs are used as launch/stop levers of the rubber-band motor. Your Butterfly comes with two sets of wings: a color one and a less bright, beige one, that you can paint as you like. The Butterfly sits on a flower-shaped platform. The elastic support slightly bounces the model, making its movements more realistic so that The Butterfly dances and flutters in the air approaching the flower.Ugears strives to share its knowledge and passion for smart mechanisms with children and adults, kids and parents. We want the complex and beautiful world of mechanics to become closer and more comprehensive. This is why the body of The Butterfly is designed in a skeleton-style, which allows you to see the working of gears and blocks inside and understand how the mechanism works.This interesting and attractive model is fun to assemble, study, and play with. It can be a wonderful present to a friend, colleague or family member. The delicate iconic design from Ugears guarantees that your new model will look gorgeous in any home or office. This is a self-assembly, mechanical model kit. Everything needed for assembly comes in the package, including instructions in English and visual. Please contact if any questions.
