The circular design is from "Celtic and Old Norse Designs" - ISBN: 0486412296. The design was converted to a dxf file using Inkscape and then brought into FreeCAD. The rest of the design was made in Inkscape and then brought into FreeCAD. The base light switch faceplate was designed in FreeCAD based on the standard dimensions of a faceplate for a single gang light switch. The designs were then extruded and cut from this base design.
