This is a simple tiny test print to see if you can get one part to fit inside the other given the given tolerance (default at 0.1mm). It also helps tune flow rate, output size, etc. The print is almost as instant as you can get for a calibration print.

The small hexagon is 3mm high and 10mm in diameter (tip to tip) .

The larger hexagon is 3mm high, 20mm in diameter (tip to tip) and 17.3mm from flat wall to opposite wall.

I do not recommend using this to calibrate Z steps/mm. Use other methods to calibrate that.
