The sony camera module I bought from http://www.securitycamera2000.com/products/600TVL-SONY-SUPER-HAD-CCD-D%252dWDR-Color-Board-Camera-with-OSD-Menu-DNR.html had obviously no housing. I wanted a printable and somewhat aerodynamic housing for it, so I whipped up something in Rhino. Printed at 0.1mm x 1mm on an Ultimaker, it looks quite nice.
It snap fits together and has access to all connectors, for the video+power connector, the control board and that one I don't know the function of. Mounting is intended on a piece of plywood into the groove, glued with hotglue (for this revision, I did not like an external nut+bolt)

Take the .stl's and turn them into gcode. I used Cura with the 'Joris' plugin. Use the provided .ini file for cura. Adjust the settings for the PLA/plastic you use. This shape is limited by the layer-cooling time of 3 seconds. If you have less cooling or your top-corners are curling up, increase this cooling time. You will need more patience then of course.

Version 4 has a little bit nicer screw holes, but if your printer has been calibrated correctly, the two parts will snap fit together. You can whip up your own without screw holes from the rhino file (unhide the goodies?).
