Rag Hanger

This design follows the jigsaw puzzle concept in previous works. The blue objects and orange objects can be assembled through the left and right grooves to achieve infinite extension. The orange objects only need to be locked with an M3*20 screw. The orange object is a rag hanger, which can be folded so that wet rags can be placed on it to dry.The blue objects are hooks, which can be used to hang some sundries, such as bags, rags, etc.
