This is my first complete model design. It is an accurate representation of a Roman Doric column. 

The height of the entire column with base and capital (top) are 7.5x the diameter of the base of the column itself. This column includes an entasis (slight convex curve) that peaks at 1.02x the base diameter at ⅓ of the height and continues to a narrower top that is 83% of the base diameter.

There are a total of 20 flutes equally spaced around the column, following the curvature from just above the base to just below the capital.

The individual STL files are for a column with a base diameter of 100mm and a height of 650mm. When you add in the printed base and capital the total height will be 750mm.

The .3mf is scaled to 25% of normal but can be easily adjusted to your liking. Be sure to scale all parts equally. The base and capital fit may be a bit tight.

No AMS is necessary and no supports either.
