This is a class assignment while studying in Russia. The topic is to use laser cutting metal to make products. I combined the characteristics of the production process and metal materials to produce the project. Because the cost of metal cutting is relatively low, I think it is more appropriate to make office products. My topic is tape cutter. To cut tape, the first key word that comes to mind is sharpness, which reminds me of cactus, so I made the product according to the shape of cactus.
