A simple calibration cube for both XY contour and hole diameter calibration.

There seemed to not be a really simple and fast calibration cube available for both, XY contour and hole diameter calibration for people using metric system in MakerWorld. I also am not really a fan of the “X”, “Y” and “Z” markings on the sides of calibration cubes available as they seem to affect the measuring results a bit, so I created a blank model.

Use the small line on top layer for aligning with certain axis (It is aligned with X-axis default on .3mf), so you know which axis' dimensions (X or Y) are off. 

3D model dimensions: 20.00 x 20.00 x 20.00 mm. Hole diameter 12.00 mm. 

How to:

• Load your machine with filament with low shrinkage % (prefer PLA).
• Print the cube with your default settings (e.g. I used 0.2mm layer height, 3 walls, 5 top/bottom layers, 15% gyroid).
• Measure the printed cube with a caliper
• Compare your measure results with the 3D model dimensions mentioned above

• (If dimensions are too much off) Adjust your “X-Y hole compensation” and “X-Y contour compensation" settings regarding to this guide: [https://wiki.bambulab.com/en/software/bambu-studio/xy-hole-contour-compensation](https://wiki.bambulab.com/en/software/bambu-studio/xy-hole-contour-compensation)

   

• → Now your 3D print dimensions are exact and come out as near as they can to the 3D model!

If you are happy with the model; please comment, like, share and boost my designs! And share pictures of prints in use!
