Hi William, Not sure why your SVG are upside down, but there are many solutions to that! * maybe it's intentionally, so keep it * if not there maybe an option during export to fix it * else: if printed on paper: just flip the paper after print out * alse: negate either x or y coordinate of all points if you have access to them. suppose your shapes are available as 2d openscad shapes, so simply use mesh() to get their coordinates and use polygon to put them back to openscad world if needed at all. hope that any of these solutionswill help you. ,, but happy to see that your joinery is working. it actually looks rather infallible, maybe even without wood glue.
