+Todd Fleming these are the files. Made with Qcad and saved in R12 and R15 format.

@Roberbike the DXF importer is misclassifying the outer path as open (R15 version). I added this example to https://github.com/LaserWeb/LaserWeb4/issues/272

Inkscape successfully converts R15 to an SVG that works with LW4. You may have to do this until 272 is fixed.
