Pinhole Solar Eclipse Viewer

thingiverse

Small one-piece pinhole solar eclipse viewer. SCAD and STL files included. UPDATE: New version at https://www.thingiverse.com/thing:2469544 is longer to give larger image of sun, assembled from 2 identical printed pieces. To use viewer: Point viewer with cross end toward sun and line up the bright dot (image of the sun) on the flat surface at other end. During partial phase of solar eclipse, the dot will be partly obscured by moon, creating a crescent shape instead of a round dot. If you are fortunate enough to view eclipse within the path of totality, when the eclipse is total, you should even see a faint image of sun's corona. JPG image files show viewer in use with late afternoon full sun (several weeks before 2017 eclipse - I couldn't exactly wait until eclipse to publish the Thing, now could I?).
