Cute Koala Bear Coaster

This is just a simple coaster I made for my son who loves Koala bears.
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.

My son already has been using it before I took the pictures which is why it has some surface issues (scratches across the top) they aren't issues with the design or print.

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