Print Face down for best results on a PEI textured sheet. It's the way I like it. Print however you like.

Printed with just White and Black colors.

I've added a no AMS STL where you print it in white and the last 0.6mm you print in black. So if printing at 0.2mm per layer as long as you switch to black for the last layer up to the last 3 layers it will print perfectly.
