Solar Eclipse Viewer

I was looking for a way to observe the upcoming solar eclipse that would work with my prescription glasses; I couldn't find anything I liked, so I made my own.

This viewer is designed to use a 4" x 8" piece of solar filter film (half of an 8" x 8" sheet available here: https://www.amazon.com/gp/product/B00DS7S52W/ref=oh_aui_detailpage_o00_s00). DO NOT use this with any material not specifically made for safe viewing of the sun.

Again: DO NOT USE THIS WITH ANY MATERIAL NOT SPECIFICALLY MADE FOR SAFE VIEWING OF THE SUN.

[ni20](http://www.thingiverse.com/ni2o) passed along some good links in the comments about safe and unsafe ways to view the sun. In particular, there are mixed opinions about the use of #14 welder's glass. Anything less than #14 is definitely not suitable, and you're probably best off avoiding welder's glass even if you think it's #14, just because it's difficult to be sure.
