Hi friends,
I don't know for you but no existing calibration cube is satisfying me.
So, I decided to create my own.
My options :
- usual XYZ cube
- spires to test the retractation
- overhang
- holes to test precision
- enough place to write informations about print conditions
- fast printing

This is that does my own calibration cube.

There is no more to tell about.
For my own, I use it with standard values : 20% infill and 0.2mm precision but, of course you are free to choose other values. If you find good ideas of values, don't hesitate to tell us in comments.

I write my informations (material, brand, color, temperatures infos, retractations infos) under the plate, directly or on a label.
Hope that will help you.

Bonjour chez vous...
