Outer diameter is correct but inner diameter in incorrect

When printing something like box and cube, my outer diameter is correct like i design it but when i put hole in middle to fit 608z bearing the inner diameter for the hole for the bearing is incorrect. Is there something i need to adjust or its normal because of abs shrinking? i want to print plastic parts for mpcnc and afraid it will not fit. Sorry for my english

All holes in printed parts end up smaller than their modelled size, just as all pegs will end up larger. The reasons for this have been recently discussed in one of the other posts under printing problems.

See those posts for the reasons, and the necessary formulae to use to obtain correct diameters.

I use 22 mm for 608zz bearings.
3.2 for M3, 4.2 for M4 if I wanted a tight fit, if smooth 3.4 and 4.4 respectively.
