The prompt

Fix my infinity cube design. Create 8 seperate solid cubes connected by properly designed flexible hingses that allow the cube to fold and unfold. Make sure there are real gaps between moving parts sothey do not fuse toghether during FDM 3D printing. The hinges must be connected to the correct cube faces and the model must usually fold into a infinity cube. Make it suitable for PLA printig.
