3D Printer Bed Level Calibration Test 3MF STL

I've included both 180x180mm and 200x200mm examples but you can take the 3MF or STL file and resize/slice to your desired size.

To start, adjust the nozzle at each corner and the centre of the print bed by running a piece of paper between the nozzle and the print bed until you feel some resistance. Then print the calibration 3MF to see how successful you were with these adjustments.

The files are 0.6mm high which should give a good indication of success but you don't need to complete the print if you are happy after the first few layers since these are usually critical indicators of bed levelling success.

INFO: In the spirit of embracing and evangelising the newer and superior 3MF file format (released in 2015) over the traditional STL file format (released in 1987) commonly used with 3D printing, I include 3MF versions that most modern slicers can use today. Please do research or YouTube the 3MF file format to better understand the benefits of 3MF over STL as we each strive f
