A very simple G scale stone type arch. It was too big to print as one piece, so I have cut it into four pieces. The raft at the legs stops the print lifting as it cools. It may work better with more rafts as I got some lift on other sections. - you can see the lift on back of the the top right arch in the photo. The "mortar" cuts on the sides are all tilted so that they print ok with the arch "on its back" as per the stl files. Beware, it takes a VERY long time to print. I did not get all the "bricks" perfectly, But it looks good when painted with sandstone type paints. Feel free to modify!
