The floral decorative 3D element you can see in the picture is actually a relief, i.e., a 3D relief model that can be used independently or as part of a more complex decoration.
Simple decorations like this are very practical because they can decorate a multitude of objects. There are a number of possibilities, e.g., try to imagine modeling a mold for soap; it is enough to create your 3D soap model, import the given floral 3D model, and "paste" it to the surface of your 3D soap model. You can produce this 3D soap model on a CNC milling machine, and then pour it with liquid silicone to obtain a silicone soap mold. Instead of a soap mold, think of a tea cup, box lid, flowerpot, vase etc. What you need is a little imagination and some knowledge and experience in 3D software, and a CNC milling machine, of course! If there is no such a machine at your disposal, you can certainly send your 3D model to a company to let them make your product or mold for you. Especially if you are starting a small production business, such a 3D model may be of great help, as it will enable you to decorate your product nicely, and thus sell it more successfully.
