This is my mod of the case modded by tnw513.

I've added mounting tabs and a cover for the camera flex cable.
In my printing, I bumped the Deltaprintr so there was a offset in the layers that stuck the 2 halves together :( You can see that in the damaged edges and the closeup last photo.
Still, with a bit of brute force, they were separated.

Also, the RasPiZeroW camera connector clip is broken so tape is used to hold it together.

The RasPiZeroW is loaded with motionEye code by Calin Crisan and just works.

Feel free to play around with it...

The covers are slightly out of alignment as I just did it by eye. And a catch to hold both halves together could be good.

The boards are held in by bending the posts a bit but melting them would work too.

EDIT:
Added another with a 16mm hole to suit cell phone telephoto lens. I've not made this yet.

These lenses are an Ebay item and just a few $.

Maybe someone else with some skill can add a screw thread to suit the lens to the case :)
