wile i don't have enough money to finish my 3d printer i am working on things to make with it. this is just something because i didn't like the normal calibration cube.i use autodesk inventor to create the stl files, so i don't know how they will come out. if anyone can give me any insite on how to better process the stl file that would be great.print and measure. i don't know if it will work or not.
