SR71 Blackbird - Sketch Art

I made my own insert for this models frame, showing a sketch of the SR71 Blackbird stealth reconnaissance aircraft. The frame is unaltered from the original model, you can find its raw file on the original models page. If you print the insert at normal speed, the text will not be fully legible, printing slower might help with that (but I have not tested it).

The source image of the sketch can be found here, it is in the public domain, as “This image or file is a work of a U.S. Air Force Airman or employee, taken or made as part of that person's official duties. As a work of the U.S. federal government, the image or file is in the public domain in the United States.”
