Do you measure your test prints hot or cold?

I'm curious if you guys measure your test print when they are still hot/warm on the bed or do you let them cool 100% before measuring? When printing ABS there is shrinkage of the part once it's cooled. I would think that you want your final part to come out to the right dimensions when cooled but that would mean that you would have to calibrate your printer to print just a slightly bit larger.

Just scale the model up by 1.02-1.05 before slicing.

i wait until cool. after all the part in real world use is not heated up again correct?

also i measure parts when taken off of the bed.

I found that's exactly what Lulzbot does with its printers. [forum.lulzbot.com]

That would be a nice feature for a slicer's filament calibration. I never remember to scale my stl files.
