Easy Read Calibration Cube

I wanted a calibration cube I cound understand when I was super new to printing. x,y, can be confusing and z? I have since then learned a lot and I wanted to give back to the community a bit.  This calibration cube is 20mm by 20mm by 20mm and was made using tinkercad. I did nothing to the cube except make the lettering a 2mm hole.  Each side is marked according to front, back, left, right and top as the first letter.  I left the bottom blank to help show what your build plate texture will look like.  Are you looking for something you can't find?
