Great stocking stuffer for your Lego fan!!! Lego Human Tool Brick Ruler Triangle 3D PLA Printed. This tool is great for measuring bricks and technic pieces. We DO NOT use a Sharpie or paint pen. This is a 2 color process so the entire ruler is printed!! No Sharpie! 3D prints sometimes have small visual imperfections. This will not keep the ruler from the job it’s meant to do.
