This is my print profile for the Roman Laurel Crown made by stevebinhobart on thingiverse. I really like it, for the size it can be rescaled to fit your head. In case, an adult male, it fits perfect the original size.

I used 0.28 layer and low infill to save material. Supports can added but not really needed. The two colors its because I runned out of silver filament.

For the STL you can take it from creator page.
