Eclipse Pinhole Mesh

Getting ready for the April 2024 eclipse. After watching [this SmarterEveryDay](https://www.youtube.com/watch?v=eNK2LI7VeX4) episode, I starting looking for a printable pinhole mesh to view the crescent sun before and after totality. I couldn't find anything, so made this one in Blender. I printed several copies in red and green to pass out at the event so people can also see the [Purkinje effect](https://en.wikipedia.org/wiki/Purkinje_effect).

It's pretty simple and an easy print.
