Interesting idea.  A while ago someone posted a picture of what looks like a 
"go/no-go" gauge for DECtape reels.  It is marked with the dimensions of the 
two sides: 2.504-2.505 inches for the "no-go" end, 2.494-2.495 for the "go" 
end.  So that tells us the hole diameter is 2.500 +/- .004.  Can 3D printing 
deliver that sort of tolerance (with hobbyist-price machines)?
