This rotating stress-relief apple features a continuous, oblique-cut, segmented structure. When closed, it presents a smooth, rounded apple shape; twisting the fruit body causes its layers to curl and stretch, achieving a stress-relieving effect through flexible deformation. It stands stably without rolling, and its one-piece construction eliminates the need for assembly. Designed for FDM printers, it is best printed using high-toughness PETG filament, ensuring it won’t break even after repeated twisting. The model has no overhanging structures, so no additional supports are required. Once printed, it serves as both an engaging stress-relief toy and a creative desktop ornament.
