Good drawing of earth's orbit for model? Possibly vector file?

Does anyone know where a 2D drawing of the earth's orbit can be found?

I would like to create a 3D printable model of the earth's orbit around the sun and slice it into the months of the year. So basically a calendar. Except I wanted to add heights for relative local weather conditions for a given year. Does anyone know the best way to draw our orbit?

How precise does the drawing have to be? According to https://en.wikipedia.org/wiki/Apsis, the Earth's orbital radius at aphelion vs. perihelion in AU is $1\pm0.0167$. That's less than 2% deviation from a perfect circle. Is depicting Earth's orbit as a simple circle close enough for your graphical purposes?

The seasonal variations in weather on Earth are primarily driven by the tilt of the Earths spin axis relative its orbit around the Sun, and to a much lesser degree by the (small) variation in distance to the Sun. In this context what do you then mean by "height"?
