All, new to the Project! Are there some guidelines for printing. For example what should the infill be for a Makerbot for strength? Another is do we add scale for shrinkage of ABS?

I am printing all my parts on a makerbot 2x. So far most of the parts fit together really snug without any scaling. A few parts needed a little cleaning up to get them to fit well. I print on the standard profile for abs and have been using 95%-100% infill for strength. I found that backing my infill percent down to 95% gives me better surface finish.
