Description

Lock the Shutter of your analog camera, preventing the camera accidentally taking a picture when it is in your Bag. You need some sort of shutter release button for this to work.

When you want to take pictures you can store the lock inside your cold/hot shoe.

Design considerations 

It works by utilising a shutter release button (I am using one with roughly 8mm diameter). The lock is placed between the Button and the film advance lever, preventing to push it down. 
It is slightly thinner than the gap between the button and the lever to not introduce stress to the shutter release mechanism but it is thick enough to prevent the shutter button pressed down enough to release the shutter. It stays in place by those small cams that have a slightly smaller cab between them than the diameter of the shutter.

The fit in the shoe is tight on purpose, so one does not lose it.

Print instructions 

No supports needed. 

I printed with 100% infill as it is so small and I don't want those small cams to break off.

Known compatible setups

Request for Feedback

I designed it to fit my specific camera (see above).

If you make it, and it fits your setup. Id like to know, so that I can add that setup to the list. (if you don't want to give feedback, you don't have to of course.)

If it does not fit your setup, I am happy to help make it fit. Either by providing models with different dimensions or by modifying the existing one or other things I am not thinking of in the moment.
