A little nice cup for your keychain. Its dimensions are :X: 30.0 mm.Y: 21.0 mm.Z: 21.0 mm.It is ready to print. I am sure of that and check it in blender. It has :Non-Manifold :0Intersections :0zero faces and edges: 0non_flat faces :0Thin faces :0Sharp edges: 0I tested in Cura, too, and everything is good.I hope when you print It not have any problem. It would be more beautiful with colors.v
