Sounds like you got it all figured out. I'd be interested to compare your original print file to a printed and scanned part to see how accurate it really is if you are willing. I'll print the same model here and do the same test. Once compiled I'll send you the report.I am no expert in 3d printing nor I have any expertise in the matter... I am just teaching myself from freely available info found on the net. It is not rocket science IMO...if I can do it, anyone can

I have high expectations from the way you are describing it.
