This is a scale model of Hermitage, a Scottish Borders castle from the middle marches. (https://goo.gl/maps/ubc1dXvKhM42) I've included the .igs file as well. The .stl file has fewer windows, since my slicer turned them into a balcony on the corners. :)
This piece is designed to be used with JAWong's excellent Catan modular tiles. It can also be used with the original cardboard board. It is to be used as the settlement (print 5) or as a city (print 4).
I printed these in PLA using elmer's purple washable glue stick on 60° heated glass with a 3mm brim. The temperature was 205° for the first layer, and 200° for the remaining layers.
