Hashibira Inosuke Coaster

This is just a simple coaster. My son likes Hashibira Inosuke from the Demon Slayer Anime so I made him this coaster using a DXF export from a sticker i made for him.
.
It is 105mm in diameter (about 4-1/8")
I believe that due to the fine detail and my use of a larger nozzle size it has a much less smooth top. If anyone has any different idea as to why it didn't do the top layer in a complete cover pass I am all ears. I am using Simplify3D with a 0.50mm nozzle.
You could try printing it face down for a super smooth appearance.

Some of the issues on top are because my son was using it before i took the pictures. Including seeing if it would fly like a frisbee (roll of the eyes - lol)

This is NOT for commercial sale, you many not put this in your Etsy store or elsewhere for sale.
