Nikon Rear Cap

thingiverse

I designed and printed a simple Nikon rear cap, testing about five of them on different Nikon F-mount lenses. Each cap fits snugly and twists on and off easily. You'll need to add supports inside the cap, as shown in my photos, since I printed it facing upwards. Some slight cleanup is required after printing, similar to any 3D print. I've also created a second cap with a slightly thicker rim. If you'd like to make any improvements or if this design works for you, please let me know.
