It's a drapery tie that I used inkscape and a modeling software to make. I recommend printing high quality because the detail in the wolf/knot make a low resolution print look bad. I used Inkscape to convert the images to dxf, extruded dxf's in freecad, converted the knot and wolf into stl files, made the block in openscad, converted the block to an stl, and finally brought all the stl's into free cad and exported a master stl with all parts together.
