This is a simple stress-relief toy model designed based on the “integrated printing” concept. Inspired by today’s popular toys, it features a unique three-dimensional structural design that seamlessly integrates seven pressable spheres with the outer shell into a single unit, offering a fully 3D-printed solution that requires no assembly and eliminates loose components. In terms of printing requirements, this model can be produced directly using standard PLA or PETG filaments on conventional FDM printers, without the need for costly flexible materials. Once printed, it can be used immediately—no post-processing required—simply by pressing and playing.
