About this 3D model

I designed the file to correct first layer in Prusa Printer iMk3, with Live first layer adjustment. If you Slices, with slow print speed, that allows you to modify little by little height of the nozzle and test in Y and X axes. This object has 1.4 mm height and 150mm by 150mm. Also I use it to test first layer in Ender3 Pro. Print and Enjoy..!!
