Clever application of everyday materials (and a 3-D printer). Nice job!

Great idea . I have experienced one total eclipse,. You'll love it :-)
Personally, I would avoid eclipse glasses , i preferred a projection.

Thanks! I've used a pinhole "camera" a couple times; the first I believe in 1963 when I was 9 years old. They didn't have eclipse glasses back then; just welding googles. I'll probably make a pinhole "camera" for this one, too. Thanks for the suggestion.
