Video: 3D Printer Sun Funnel
The Sun Funnel is a device for telescopes that allows a group of people to observe a magnified image of the sun safely. Instructions, warnings, and tips for using the original Sun Funnel are at http://tinyurl.sunscope. Students of Career Academy South Bend have designed a 3D-printed version of the Sun Funnel to witness solar eclipses, transits, and sunspots, with 3D-printing files (.stl) and more on the Sun Funnel page (URL shortened to http://tinyurl.com/sun3D).
The 3D Printer Sun Funnel debuts June 10, 2016, at the American Astronomical Society (AAS) Eclipse 2017 Workshop (#Eclipse2017Workshop) in Carbondale, IL.
