The links to the Cricut cutting machine files are in the assembly instructions PDF, but they are also included below. In order to use these, you would need a Cricut cutting machine, and to have Cricut Design Space installed.
I am not aware of a way to directly convert these Cricut files to the SVG file format for other cutting machines. If you have a different type of cutting machine, I think it would be necessary to open these files in the free Cricut Design Space software, print them as images, and then convert the images to SVG. If you prepare the SVG files, please send them to me so I can make them available for others here!
