This is the Gingerbread house that required no support to print it out.
The back is sliced off, but still looks good in or out of it's box.
Print it, the front will look a little more like gingerbread layers as it's on a slight angle to help the roof features print.
The points on the roof should print fine if you use 0.2mm layers or smaller. Use 2 or 3 solid layers.
