Based on the model I had made earlier, I calculated the new dimensions and then cut out the shapes for the unfolding of the drawers using laser cut steel plates.
The second part was to bend 90° on the machine and then make the integral drawer shell.
The discovery here is that the steel itself bends so hard that the two pieces fit together so well that it doesn't even need a river to hold it in place, and I wonder if this is a new environmentally friendly method of assembly.
The difficulty encountered here was that because of the thickness of the steel itself, and its own hardness, the bend was not exactly 90° perpendicular, so the internal drawers would not fit in because of these errors.
So I re-cut it, calculated the errors that would occur, and then reduced the internal drawers a bit。
A new problem encountered after assembly is that the drawer track is not restricted, so it causes the drawer to fall out when it is withdrawn beyond a certain length.
Handle design:
During the laser cutting process, I saw that there was some discarded material, such as the shape with holes left after cutting the circle, just enough to put a finger in and then use as a handle. But this time I didn't use the discarded piece of material directly, because the laser had already cut it badly.
