With the October 14, 2023 solar eclipse just around the corner, I was looking for solar eclipse binocular filter lenses. Prices were a bit much for just a single lens. I then came across Solar Filter Sheets that can be used to make your own.

So I made a filter sheet lens holder to fit the binoculars I already had.

Simple steps to make your own:

  1. Use the OpenSCAD model to custom fit this to your binoculars. 
  2. Cut a circle out of some Solar Filter Sheet material to fit inside the lens holder
  3. Place the solar filter into holder,
  4. Secure the lens snap ring into place by pressing it all the way into the lens holder

CAUTION: Be certain that the lens holder securely fits onto your binoculars and completely blocks out stray light. You can seriously damage your eyes if exposed to sunlight. I'm in no way liable for use or missus of this design.
