How to get camera out of the plastic case.

I need to get camera out of the persipex casing to clean sensor. Sensor definitely has some smudges on its surface, because they can be seen on the video. As well, I need to solder the pin headers. One can clearly see gohstly bluish patches in the bottom left and bottom right corners.

but I can’t find an outside latch on the sim that goes around the case. I should hate to brake the nice casing just for one off opening.

Any good advice?

Hi, on the left side of the case there are two holes for a flat head screw driver. Stick the screw driver in those two holes and turn it. The case should pop off.
