You’ve gotten a number of good suggestions, but I’ve got one more. Someone – I want to say a branch of the Smithsonian – took apart a scanner so as to situate things so the scanner could sit above the item to be scanned (they also rigged a system to raise and lower the object ).
Does anyone remember seeing this? It was on a video online. I thought it was a C2C webinar, but looking at the archives I can’t find it, and I’m apparently not googling the right thing.
If you encounter this situation often, this might be worth the time to rig.
