Dimensional correction test piece

Here's a dimensional test object I created to calibrate my printer and make sure I was printing dimensionally correct parts. The end result of this process is accurate scale figures you can use to make sure parts fit tight tolerances. The piece includes 6 100mm measurements in the X direction, and 6 in the Y. The protocol I used was to measure each of these 3 times, giving 36 total measurements. It's not very easy to correct for X/Y skew in bambu studio, however, using this piece I was able to determine that the scale factor I needed for dimensionally accurate ABS, was equivelent to what the thermal expansion was. I can imagine a use cases for this print: making sure your printer is dialed in, determining if you have significant X/Y scaling issues (not a problem for me), or determining the scale factor you need for a new material.I've included a sample calculation here: https://docs.google.com/spreadsheets/d/e/2PACX-1vTmJj0n_KWD1p4YhHnH3_yh-n6kqhBvkYMBoA1sziJdUuPQxl_UmbK5K7
