This is just a remix of numerous different covers (Main inspiration was the design by NeoHeldt) for the raspi/arduino camera.  I ran into a lot of models and anytime I printed them the holes didn't always line up with the camera circut board and I didn't want to risk ruining the camera forcing a screw through it so I decided to re-design the case and move the screw holes to go just through the case and put pegs for the camera to fit on to hold it steady in place.  I also designed this to fit on an arm for a camera mount designed by HippieHeadShot (https://www.thingiverse.com/thing:3095730).  I really liked this design for a camera mount and it can mount the Raspi Cam using this case or it can mount a webcam.  The screws for the case are M3X10 and the screw to mount to the arm is an M4.  The screws for the case may need to be melted in a little as the insets may not be quite wide enough.  I will upload a new version at a later date.
