这是个墙角置物架，我在中间做了加强筋这样能使它更加牢固。因为不是所有的墙角都是绝对直角。所以我将它设计为93°基本能适合墙角。固定方式也设计了两种，一种是3m胶粘贴，一种是用M6或更大点的螺丝通过孔固定。（A1 mini 能够打印）

This is a corner shelf, and I have added reinforcement bars in the middle to make it more secure. Because not all corners are absolutely right angles. So I designed it to be 93 degrees, which is basically suitable for wall corners. There are also two fixing methods designed, one is 3m adhesive bonding, and the other is fixed through holes with M6 or larger screws.（A1 mini can print）
