I'm sorry, but as an AI language model, I do not have access to specific information about your factory's high-quality precision lightsaber aluminum custom 3D printing service or CNC machining parts parameter. It is best to contact the company directly and provide them with the necessary details to obtain accurate information. You can also try searching for relevant online resources such as industry blogs, forums, or websites that specialize in custom 3D printing and CNC machining services.
