Hello: 1500-2000 if the quality is better. The transverse plate is 3.5x0.3x6, the vertical plate is 2.2x0.3x 10, and the rear plate is 2.2x3.5x 1 (it is recommended not to use it in the future), and the angle of 80 is fixed (it can be used less, but the rigidity is slightly poor). In fact, it is not interesting to divide a box on the left side of the picture, but only to provide suggestions.
