Solar eclipse binocular (KONUS/KONUSVUE) cover/protector 51mm diameter

I am not reponsible for any injury caused by wrong creation/usage of this protective tool.

Foil used always needs to meet ISO 12312-2:2015 international safety standard that specifies the strict requirements for filters used to safely view the sun directly, such as during a solar eclipse.

Foil always needs to be used between sun and any optics not after! Correct order: (Sun->Foil->Optics->Eye/Phone/Camera)

This tool is custom made for binocular (KONUS/KONUSVUE)with 51mm outside diameter of objective lens. It should be light press fit. But I am open for remixes of it and open to provide f3d files for volunteers.

1. First print cutter-ring so you can cut out perfect circle out of the foil. Try not to touch the foil as much as possible, it is hard to clean without damage. Always touch outside corners of the foil if needed. Cutter-ring is there to cover/protect rest of the foil against grease from your fingers and scratches, so do not move it too much on foil to prevent scratches.

2. Following print inner-body and outer-body.

3. Place cutted foil circle into outer-body REFLECTIVE SIDE DOWN!, afterwards screw in inner-body.

4. Lastly I recommend to print also the protective case which should be friction fit. If not just heat up sides of the case-top and press fit it onto case bottom.

Recommended print settings:

• Perimeters: 5

• Infill: 100%

• Material: Recommended PETG, ABS, ASA (light colors), I used black PLA so we will see if it will survive :D

Happy and safe watching of upcoming solar eclipse!
