Getting good dimensions on a test cube is good, but it’s only half the story. A lot of the critical fitment points are internal (screw holes, nut traps), which are affected by different parameters than the outer dimensions. A good calibration guide can help you dial those in. Here’s a good place to start: http://www.reprap.org/wiki/Triffid_Hunter%27s_Calibration_Guide.
All that said, I think you’re okay as long as you’re close. I had to drill out the screw holes and do a little sanding on the pieces that bearings get inserted into, but it wasn’t difficult and didn’t take long. The tightest fit I had was on the corner blocks, and I created a wedge that opened the block enough to get the conduit in – problem solved.
