Shutter Button Lock for Nikon FE and Leica type buttons

thingiverse

Shutter button lock for long exposures. Made for my Nikon FE but should work with any Leica-type thread. The button can be simply pushed and work with any mode or can be locked in the down position to take long exposures in bulb mode. I printed it in resin with my Anycubic Photon 4K. It needs to be printed floating with supports. There is a small ledge in the button so it cannot disassemble so make sure to print the two pieces as they are with the threaded part on the bottom. It doesn't require a spring for the Nikon FE because it rests on the shutter button. It shouldn't vibrate too much when pressed and released. It is designed so it can be operated as a normal button but for the lock to work you probably need to use 2 hands to reduce vibrations to a minimum. To reduce vibrations even further gently press it when you want to unlock it.
