Printable Shrinkage Calculator

Yes shrinkage is not just about cold water!!! I've looked at some spreadsheets that claim to calculate shrinkage, but they never gave me the results I was looking for, so I came up with this instead - you can print it out and measure for yourself if you like. I've made a PLA version with a 0.4 nozzle (the lettering didn't turn out right), then another one with a 0.2 nozzle and it looks pretty good and the dimensions are exactly the same. I'm going to make an ABS version as well and compare the two.
