Neo1973 drawings

[Sébastien Lorquet]

If someone gives me left-top-front etc views of a neo case... I can try to
do something with SolidEdge (academic version of SolidWorks). I can't
promise exactly when, maybe this weekend.

(And it would be helpful if neo's curves were circles and not complicated
splines... :D )
