The prompt
Create a 3-D printable infininity cube fidget toy made of 8 small connected cubes. The cubes must fold and rotate smoothly into diffrent configurations. Use simple strong hinges that can be 3-D printed. Make it suitable for an FDM 3D printer using PLA filaments. The model must be correctly sized, with enough clearence between moving parts so they do not fuse toghether. Export an STL file. Prioritize a functional, durable mechanism over appearences.
