It… umm it's umm a bendable drought. I think. If you are using a 0.4 mm nozzle size it down 10X less the the actual size. I found out that I forgot to scale it down on Fusion 360, Prusa Slicer, Blender, or if I wanted Tinkercad. Do NOT bend it too much on the bottom or it will you know be a little different and then break. Only bend it until the little blocks meet or else it will break. Do not take it of directly with your hands or use a scraper when the print just finished. You have to give the first layer some time too cool if the print bed is on a high temperature. It's kind of fun to play with. Use a smooth PEI sheet when printing so it can look good. Use ironing   if you prefer quality over speed.
