These were meant to cut out by a Cricut or Sillouette machine. I was able to convert the svg file i was provided to an STL but when i opened in Cura the print space is now the empty space and the printed pieces are what should be empty or serve as a border. How do I go about inverting the empty space with Fill space and the printed stencil pieces with empty space? I am at a loss here of if this is possible to correct or even how I would take the pngs attached and turn them into a stencil that is printable . I am working with and Ender 3 printer btw roses_2 part.svg_10mm.stl
