1st time printing with ASA and it’s my largest print that doesn’t have any straight lines. I typically only design things with straight lines, pretty pleased with how this turned out. Threw in a cactus to fend off the cats but fortunately they don’t seem very interested. Printed on a Bambu X1 carbon with Polymaker ASA.
Depending on if the seam is concave or convex, you might be able to use a file or thin piece of fine sandpaper to remove it, but you might wind up with an ugly scratch worse than a uniform line.
Either way it still looks very nice.
