Sony A7 Black Out Camera Ring Remixed
I tried Cinean's camera ring and it was slightly off for my A7S ii camera. So, I remixed it in Tinkercad. This ring has a slightly thinner lip and a larger cutout so that it doesn't interfere with the button to change lenses.
I printed in PLA and it is a tight fit on the camera, but because it is thin, it fits. Hope this helps. I really like the original design.
