Raspberry Pi Camera case and support version 2

Version 2.

I have now updated this case to allow more clearance between the friction fit items - it is still a tight fit, but you wont break the parts when you assemble them.

This is a case for the Raspberry Pi camera module that will connect to a 22mm extruded aluminium frame of most delta printers.

Each part is optimised to not need any support structure and should not need support structure. It should also fit together using friction only, and will not need any nuts, bolts or otherwise.
