For my Key Buckle 3D print, designed as a small side-release buckle or parachute buckle to serve as a quick-release mechanism for bicycle keys, I utilized both the Creality K1 and CR-10S printers. The Creality K1 printer was used for its efficiency in producing detailed and functional components, while the CR-10S printer was employed for the main body of the buckle. The PLA material was chosen for its balance of strength and versatility. During the printing process, supports were needed under the Male Key Buckle part to achieve the desired shape and functionality. The combined use of the K1 and CR-10S printers allowed for precise and accurate printing, ensuring the buckle's parts fit together seamlessly. This practical and versatile design provided an efficient solution for quick-release applications, such as securing bicycle keys or other items.
