About measuring : unfortunately I have a hard time trying to be sure about the exact distances. What's sure is that it has to be more precise than half a millimetre. I do not have tools that are precise enough.
About scanning and rescaling... I could do that (and already did in the past for other gear), but if someone (Mr Dieter Doepfer perhaps ?) could give the exact dimensions, that would be far better, more precise and faster...
