Hello. I am working on a a project that combines plastic and metal components. It is a detailed spinning top made with plastic with metal towards the outside to give it centrifugal force while spinning. My only problem is that after printing it, I found that the parts didn't fit, despite fitting in my 3D model. I was using polished bronze steel and processed versatile plastic. It sees that the metal was coated with something causing the outer edges to be too big, and the holes in it to be too small. For my next printing, what metal material would you recommend for the metal segment? It needs to be durable and hopefully heavy. Would aluminum work? Is there anything heavier than aluminum that would work? Thank you!
