3D Puzzle Butterfly for CNC or Laser

I remixed the original design by jtronics. Main changes include:

• Scaled for 3mm media (original was for 1.65mm)
• Nested the shapes to fit within the smallest possible bounding box (see Lightburn file)
• Nested the shapes again to fit the material I had on hand (bounding box 271mm x 377mm, or approx. 12in x 15.25in)
• Added more sprues to hold the shapes in place
• Added a small hole for hanging the assembled model, as close as I could to the center of gravity (not tested yet)
• Added a quick logo and "Lasered by Brad" text -- files provided as examples, or in case your name is also Brad.
• Added a license statement
