Use 5 trapezoidal blocks and 2 triangular blocks to form an H letter.
The two triangular blocks are 1×1 isosceles right triangles, the three smaller trapezoidal blocks are right-angled trapezoids with upper base 1, lower base 2, and height 1, and the two larger trapezoidal blocks are upper base 2 and lower base. 3. A right-angled trapezoid with a height of 1. As for the thickness, just stick a few more pieces to exceed 1cm.
There are two copies of the graphics in the PCB, which are pasted together to increase the thickness after the board is printed.

Cut along the white silk screen (the 1.6mm board is much harder than I thought...I can't cut it)
