Binocular eyecup for Bausch & Lomb

Bausch & Lomb made nice binoculars that were branded by Natl. Audubon Society.  The company sold that business, and rubber eyecups for this 8x36 binocular are no longer made and impossible to find.  These were made with black TPU, so I tried to keep it simple.  They don't fold back like the original rubber eyecups, but they fit nicely. If you wear glasses, you could shorten them.  The scuffs in the photo were post production sanding; I didn't want them glossy there. Supports were not needed.
