About this 3D model

My niece ask me some time ago if i would make a bracelet for here. So i ask: what kind of bracelet do you want? She says one with little hearts. So this bracelet is what i came up with. I'll hope you will enjoy it as much as she does. Measurements: 70mm x 60mm x 30mm And thickness of 5 mm I'm not really sure what happens if you scale this model. I only made it once. (sorry for my bad english)
