I tried printing this with and without supports, and either way I had issues with the ceiling inside the hut. I recommend printing without supports , ideally the problem areas will be hidden underneath but you can also use some putty to clean it up if you prefer. I printed the one in the photos at 250mm wide. But you can go wider or taller if you prefer a larger piece. If you're on a smaller printer, turn the piece at a 45 degree angle so it can be printed a bit larger. The one in the photos would fit on an Ender 3 when rotated properly. These tufts of grass and sprinkle-on moss really made this look real, I used a gloss coat spray to make it look shiny and wet and the sprinkle moss stuck right on.
