For my National Parks 3D Prints Project, I have relied heavily on using photos I took and therefore own the copyright for. However, I am at the end of the parks I have been to! To see a list of parks I am looking for photos for please click here. If you have a good photo (or even four to support my next project) please contact me. You just need to own the rights to it and be willing to grant me the right to use it for 3D prints. Any STLs, for this project, will be made feely available. This means that anyone, with a 3D printer, will be able to create the Lithophane on their own!
Also, don't care for the photo used for any given National Park? If you have the photo I will be more than happy to design a lithophane with it! Just Contact me!
