Nikon eye cap

Nikon visor cap, usefull to take long exposures or take dark frames or biass for astrophotography and prevent light enter through eyepiece.

Works in my nikon D40. I have not tested in other cameras, but probably it should work.

External dimensions of my D40 eyepiece are 24.9x15.8 mm.

Print in black filament.

If printed vertical supports not needed.
