Where to purchase a perfect beverage can model?

Hi there!

Where can I purchase an OBJ or similar representing a 0.5 liter beverage can in perfect quality? The latter means especially smooth round shapes to me. Or is this a »technically impossible« demand?

Virtually every OBJ I tried gives me jagged curves and rims (as shown in the screenshot) when rendered, which is not acceptable for me in this case.

Thanks a lot!
