Bought A Brass version at a yard sale, been using it as a paperweight. If the STL doesn't seem to be scaled right , then adjust so the the Paperweight is 4-1/4 inches wide and 1/2 inch thick. Never found out why STL change scale when exporting from the original Sketchup drawing.. Sketchup gives choices when exporting an STL to either ASCII or Binary, as well as either Inches or MM. Anyone know the answer ?? Let me know if you do.... Thanks !!
