I haven't seen any interface for output scale or level of detail in regards to STL output. For example, my last 3d printed model experience involved getting a callback from the printer asking me if I knew my model size was slightly larger than a dime. No, no, just make it about the size of a 6 inch box, I said. Perfect results came back from my local library at a cost of less than 12 bucks. Where is the interactive interface where I can predetermine scale and level of detail? I have a model which is inexplicably generating a 400MB file size. From here on, I'd like for all of my pieces to be printed to scale for comparison reasons. How do I get that?
