Lomo LC-A multiple exposure knob

thingiverse

I have modified my LOMO LC-A with some features that are only possible on the LC-A+. The shutter button and front plate come from a broken LC-A+ but were modified to fit the LC-A. To take it to the next level, I added multiple exposure capability! First, you'll need to make a hole in the bottom plate of the LC-A, approximately 3x8mm big. Early models have a slight indentation on the inside that makes it easy to find where to make the hole. If your camera doesn't have this indentation, try finding the position by looking at how the mechanics move when advancing the film. A metal pin can be moved to cock the shutter. Once you've made the hole, simply add the printed slider and you're ready to take multiple exposures without any issues! One important note: since the part is very small, I recommend printing 2-4 at the same time to let them cool down and ensure you get at least one good one. If you want to design your own, consider making the bottom plate slightly thicker and rounded.
