Bed Calibration Square

A simple bed levelling square that takes up the entire bed (180mm square) for my printer (Monoprince Maker Select v2.1).

It is 0.2mm "thick" -- so set your layer height to that. Single top/bottom layer also.

Use to determine how good my bed is levelled everywhere. You can later measure with caliper to see close it is to 0.2mm (thicker means bed was too low, thinner means bed was too high).
