This model for 3d printting. Units millimeters 330x310x550mm (Scale it in your slicer program if you want minimum size). I recommend you use 0.4 mm resolution (But you can try something else. It doesn't so much matter). Rafts: No. Supports: Yes. Infill: 30% (But if you want it so much heavier use 100%) Use STL for your slicer program. Glue parts № 1,5,2,4 as shown in the picture . Use maximum supports for part №6.
