solar filter for binoculars

thingiverse

This is a holder for solar filter film that allows you to quickly install and remove it from your binoculars to view sunspots and planetary transits. The idea is simple: attach the solar filter film online, cut it to size, and insert it into the printed holder. Two covers come with each holder to keep everything organized. I have also included a scad file so that you can modify the print design if needed. However, make sure your binocular tubes fit perfectly with the holders. You should feel secure when looking at the sun, without any chance of the holders coming loose. Always cover both tubes and never look directly at the sun without securely attached filters in place.
