Pull Copter (Supports A1 mini)

This 3D printed spiral bamboocopter is a perfect fusion of traditional toys and modern manufacturing technology, designed for enthusiasts who seek both fun and performance. It consists of three core components: a propeller guard ring, a spiral rod, and a connecting shaft. The entire structure is printed using lightweight PLA filament, with a single finished set weighing approximately 11 grams, achieving extreme lightness while ensuring structural strength

In terms of design, the spiral rod features a unique wave texture, which enhances grip friction and efficiently converts into lift when rapidly rubbed. The three-spoke guard ring effectively prevents propeller blade deformation while ensuring safety during play. After printing, no complex assembly is required; simply pass the spiral rod through the connecting shaft and the propeller blade's central hole to complete the assembly

In actual testing, by simply rubbing the bottom of the spiral rod quickly with your palm and throwing it upwards, the propeller blades will spin at high speed, generating strong lift, flying effortlessly over 5 meters high. It hovers in the air for a few seconds before slowly descending, recreating the classic fun of childhood. The 11-gram filament consumption not only controls cost but also gives the toy excellent portability. It can be carried in a pocket at any time, allowing for flying fun outdoors, in parks, and other settings

This bamboocopter is not only a nostalgic toy but also a vivid embodiment of how 3D printing technology integrates into daily life, allowing traditional fun to be reborn through modern craftsmanship
