Nắp che thân máy Sony E-Mount

Bought a used camera, and it did not come with the cap for the camera body. I wanted it to have both the alignment marker, and to clip to the camera. I have remixed another cap before, but decided I wanted to make my own model from scratch. 

Fits perfectly to my Sony A6300, and therefore I assume it fits just as nicely on other Sony E cameras. 

Might be a bit snug in the first couple of times it's put onto the camera. 

I am also making a version that will be a Funsaver disposable lens.
