Dimensional accuracy of printed parts

I’m starting the task of printing out the parts (PLA), and I’m wondering what is acceptable dimensional accuracy? As a test, i printed out one of the corner block locks, and the z dimension was off by ~1.5%, and the y and z by ~1%.


I’m sure that will be fine. If you are worried it sound like all three axis are off by at 1% you can always scale them up by 1%. Best option is to run through your printer and make sure the calibration is right. maybe you are under extruding a bit. Try the 100mm extrusion calibration and double check your x y and z steps.
