This will project sharp and fuzzy shadows during a solar eclipse, as well as a pinhole projection of the eclipse itself. You'll be able to see how alignment with the solar crescent affects the sharpness of the shadows.
I designed in inches, you'll probably need to scale by 2540% in your slicer. The thickness works best at .25", which makes the area around the pinhole projector a single layer on most machines. If you need to scale it to fit on your print bed, leave the Z-axis unchanged and scale the X and Y axes the same amount.
