Cap for Nikon F-Mount lenses

thingiverse

This F-Mount lens cap replica is sturdily designed for a perfect fit on Nikon lenses. The close-to-original design ensures seamless integration with your lens. For optimal results, print it using PLA instead of ABS to avoid warping issues. Sand the part that touches the lens with fine grit sandpaper (120 or higher) to achieve a snug fit and smooth surface. An improved version is also available for hassle-free fitting.
