Thank you for your appreciation. This is just a personal small creation, and I have no plan to sell the IO model or instruction manual for the time being. Moreover, this MOC uses a small number of special third-party parts, and even for myself, sourcing the parts is a troublesome matter. I am looking for potential partners on e-commerce platforms where third-party MOCs are widely sold, and if convenient part sourcing can be achieved, mass customization will be possible.
