Snapmaker bed level test

My version of a bed level test specifically designed to suit a Snapmaker V1's bed.

A couple of recommended settings;
1) 0.4 nozzle
2) 0.3 initial layer height
3) Concentric bottom pattern (Cura)
4) No skirts, brims of rafts

This should give a single layer print with a single line border and 20 lines within the pattern to ascertain if the bed is level and flat.
