I would recommend printing this print on it's side if you are worried about the print quality however you would need support material

Generally, printing as slow, cool and in thin layers as possible, improves quality. But obviously, it also increases time quite a lot.

 

In CAD, cut out a small part of this model with complex features, and try different settings on that, so you don't waste days on a full print.

You should be able to print this vertically without any support (except maybe near the very bottom) as Zarkhowler suggests.  You'll be amazed by the quality improvement on the front of this print if you print it vertically.

 

Well the flat area of this coin(?) appears to be just a little non-flat.  Like a coin wrapped somewhat around a cylinder.  If you make it truly flat in cad then it should print a little nicer (assuming you still print the coin flat.

 

Overall this is relatively good quality for such a small item.  But to get it better I would use a 0.25mm nozzle and print with 0.2mm line widths.  Or even go smaller.  3dsolex sells nozzles down to 0.1mm (human hair diameter) which you can print down to around 0.075mm.  4X higher resolution and 16X slower than printing with a 0.4mm nozzle.

You could split up the part and print them at diff. Orientations to get the best quality and reassemble with glue or a snap fit or press fit. This is not always the best way as its tedious printing all of the diff. Part and reassembling.
