Eclipse Pinhole Viewer (Conical)

This is a pinhole indirect viewer for the solar eclipse.
I figured that we might as well make this thing a cone so there's no need for supports.
This is UNTESTED... so tell me if I need to adjust angles or whatever. (It's been cloudy lately and I've only tested roughly with an LED flashlight)
Thanks!
Please be careful, you can possibly poke your eye out with this if you run too fast!
You might want to add a cloth or paper on the inside of the base if your top layers are too textured.
