 I learned to use the Laser cutter @ Fablab Kamakura during FabAcademy. The document is [here](http://fabacademy.org/2019/labs/kamakura/assignments/week04/).
    
 I Cut the sliced pattern using laser and assembeled as follows. But... I couldn't insert one parts at my sholder area. Ummm...   I should have checkd carefully before cut.

 The material used was junk acrylic. During the Covid19 pandemic, offices used acrylic partitions between people, but now they are being discarded in large numbers.

--  Material
-    - Junk acrylic board
-        - thickness:  5mm
-        - Size: The size of each piece is different because they are cut randomly to fit in the junk box. The large ones are about 25cm x 50cm, but many have an oval hole for carrying them.
+There are two types of laser processing locations as shown below. The blue line is the outline cut, and the red line is the stacking order and location marker. First, the blue line was cut in Vector mode, and the red line was engraved in Raster. However, I realized that Raster takes a long time, so I decided to weaken the power of Vector and mark it.

+You can check the time required for processing on the tool screen. In this case, the blue line takes 22.07ms and the red line takes 25.26ms. This time, I used the following junk box materials, so I didn't cut them all at once. In other words, because I selected and cut parts of the design to fit the free space on the material, the working time was longer than the time on the tool above.
