Yashica 35-70 plastic lens mount

thingiverse

This is a replacement back mount for a Yashica ML Zoom 35-70. I design based on the original mount, making minor modifications. I've already tested it in my lens and in my camera. It was designed to be a bit thinner than the original, in order to accommodate 3d printing tolerances, so it may focus a bit beyond infinity. I suggest printing it with the mount facing up.
