Binocular Lens Cover

I lost the lens cover on a pair of binoculars. Fortunately, I had a second pair. I modeled the rubber lens cover and reworked the hinge to work better in plastic as the original is of rubber.

The part that I used for the model is: https://www.amazon.com/dp/B095KH1CMN?th=1

Support 'on' for inside the caps.
