3D model description

Updates:
* Aug-10 2017: 2.0 update. Was not happy with uneven clamping. Increased clamping screws to 6, decrease mounting screws to 2. Tweaked front cap to maybe print better in ABS.

  • Aug-9 2017: Added a notch to outside of rings and inside of hood to ensure alignment. Made some screw holes bigger for ease of assembly. Added a front cover (currently un-tested).

This is a redesign of my first version I posted a week or two ago. After being un-impressed with the cheap solar filter film I got on Amazon I ordered a sheet of BAADER solar film. When it arrived I found it to be much much thinner than the other film, similar to tissue paper. I knew that my last design would not hold onto this material, nor hold it taut. Thus the redesign.

I will look into designed a front cover for this in the coming weeks.

Materials needed:
2X M3x12(or 14) screw.
6X M3x8(6 might work) flat head screw (flat head not required, just looks better).

I designed this so you're able to align your film onto a holding ring, and then install that ring inside the lens hood. I highly recommend you TEST this out on something cheap and similar to your solar film. If using the Baader film I'd recommend using a mylar "emergency blanket" as a test material to get the feel of installing a film.

You want the film to tight, but NOT STRETCHED. Stretching a solar film can lead to degradation of it's filtering properties. This could cause blindness, and damage your camera!

This is where I ordered my solar filter film.

This was my original design. Still may be useful for thicker solar films. (https://www.thingiverse.com/thing:2435107)
