Reflex Sight Cover

I have this sight for my telescopes (not weapon), which needed a new cover, the original rubber one was perishing and getting a bit funky.

This is a cover for a generic type reflex sight as in the pictures.
The fit is loose, I put two pads on the inside (sides) which holds it snug, and may prevent scratching of paint on the sight.

If you are printing with some flexible filament, you may need to shrink it a percent or two for a snug fit. I have never used flexible filament so I do not know for sure.

Enjoy.
