Eclipse / Sun Viewing Lens Frame

thingiverse

This frame is designed to hold a standard-sized shade #14 welders glass filter for viewing the solar eclipse or general sun observation. The lens measures 2 inches by 4.25 inches in size, and it's crucial that you use only shade #14. Take a look at the photo provided and you'll know exactly what to order. I managed to source the lens from a local welders supply shop, which still had an ample stock as of August 15, 2017. The sun appears greenish but has excellent optical quality. To give you a better idea, I paid $3.25 for the lens, so with the tip included, you'll be spending only $6.25 in total.
