150 x 150mm Calibration square

thingiverse

I found the 20mm X Y Z cube wasn't big enough to give an accurate calibration. https://www.thingiverse.com/thing:214260 So I made a simple 150x150 square which gives a much more accurate result due to being much larger. Print in vase mode (spiral mode) to conserve plastic and reduce print time.
