50mm aperture for large format camera

Remixed with a quick fix to ensure the leaves don't pop out of the grooves when closing the aperture. The better solution would be to move the pin on the leaf farther out. I also included some pins to fasten the body together. Insert them and melt the end to fasten. And, a recent addition is an alternative base which is part of the cover for the leaf shutter found in my designs. This helps integrate both units so they don't have to be glued together.
