Nikon Flash Sync Threaded Cap

When I purchased my beautifully aged Nikon F3 it didn't have a cover/cap on the flash sync port so I created this. Please be careful to use the same settings that I did for the best results. Also, the threads are very fine for these flash sync ports so it might take moving around the cap slowly as you start to thread it in but I assure you it works and will fit. This works for my Nikon F3 but I'm not sure what other camera bodies it might work for.
