Most of the scaffolds in China are made of iron, which will rust and corrode for a long time, so I designed this stainless steel mounting bracket. It is strong, durable and corrosion resistant, and the cost is controlled at $20. Since I do not know about the foreign market environment, I plan to sell it on Amazon. I do not know whether there is a market. Because China's manufacturing industry is very complete and the cost control is very good, so I want to use MOI 3d to design some practical hardware products and sell them on Amazon. I don't know whether this idea is feasible.
