20mm XYZ Calibration Cube 

Use this cube to measure your printer's dimensional accuracy. All axis should measure 20mm thick. 

Reasons that the calibration cube might be under or over sized:

• Filament shrinkage
• Filament flow is incorrect, or filament diameter is incorrect
• Printer is not calibrated correctly, or the printer is malfunctioning
• Solar Flares

Notes to consider when printing this:

If you want to print at realistic speeds when printing this calibration cube, make sure your printer will not slow down for short layers. The main profiles made by me have this setting turned off for its Bambu PLA Basic filament preset. If you change from this filament preset make sure the preset you do choose has the cooling slow-down option off in Bambu Slicer in the filament settings (as seen below). If your calibration cube is over-heating, then you may need to print more than one calibration cube, or increase the cooling.

Please take note of the circled setting in the screenshot below if you are using your own filament settings:
