Gridfinity Refined - Baseplate Spacing. I noticed that a 2x2 grid is not exactly 82mm width but 81.5mm. A 1x1 grid is not exactly 42mm wide, but 41.5mm. So each apparently has 0.5mm tolerance. When I assemble a larger grid from smaller grids, wont this add up as error? Pic shows 2* 1x1 != 2x2 width.
