I am trying to print something very thin, 0.8 mm tall that has a large flat surface area, about a 3 in diameter circle. What is the best way to get a good top surface? In the pictures, you can see that the top surface is not very even and the bottom has striations running across the bottom.

Your bed is going to need to be perfectly leveled to get a perfect print with something that large and so thin. Otherwise, the impact of a slightly off first layer will impact the entire part.
