我家有两个路由器，为了避免墙壁上在多打个孔 我画了个这上下两层的支架，用3M胶固定在墙壁之上。长200mm，宽200mm，高140mm。

I have two routers in my house, and in order to avoid making extra holes in the wall, I drew a bracket with two layers of upper and lower layers, and fixed it on the wall with 3M glue. It is 200mm long, 200mm wide and 140mm high.
