Binocular eclipse filter 53mm

thingiverse

I needed a piece to hold filter material for an upcoming eclipse, so I designed this to fit my 53mm diameter Leupold 10x42 binoculars. It provides a nice press fit on those, and should work with anything that has the same size objective lens. These also allow me to use the normal lens caps to protect delicate filters. If you decide to use this design, make sure to use safe, ISO-rated filter material. Taking shortcuts can cause blindness in an instant. When magnifying the sun with binoculars, milliseconds are all it takes to blind yourself if your filter material is sub-par.
