Model for 3d printing. You can scale it if you want. I recommend you slice it for different parts and then glue them together. Use 0.4 mm resolution (But you can try something else. It doesn't so much matter). Rafts: No. Supports: No. Infill: 15-40% (But if you want it so much heavier use 100%) Use STL for your slicer program. If anything you want to change in the model use another files that more fits you
