Trying to make a seamless pattern that mimics the look of Lego bricks.

Trying to make a seamless pattern that mimics the look of Lego bricks. I have a set of maps, but for some reason, they seem to slip as you move up or down the model.  I am using the brush to Keyshot bridge not sure how this affects the scale.  I have attached a render any suggestions would be super helpful.
