This object has a diameter of 30mm and a wall thickness of 1.2mm which works so well with a head in 0.3 than 0.4 mm. It is expected to be 80% filled but it can print in another value.
Personally, I never knew how to print it correctly because the lower part of the sphere poses problem and I am not yet familiar with my printer.
If someone prints this object correctly, it would be nice to put in the comments all the elements necessary for the success of the printing.
thank you in advance
