ns switch 3D model

NS split modeling (each feature of different colors is an independent entity, so UV mapping is not used, and merging / operation can be carried out if necessary), high-definition mapping on the back of the host (the back mapping is made by entities, which can ensure the clarity in extreme cases), the bottom barcode, and the host seat are added. Among them, the mainframe adopts inventor parametric modeling, which can be re edited in inventor.
