The child was given the task at school to bring models of geometric shapes.

I did not find any free geometric shapes on the site, and suggested that the child design them himself. He did it in the Compass 3D program.

Slicers installed on a home computer sometimes make unsuccessful supports.

A ball that has a shape with a very small support surface will most likely not be printed without supports. Therefore, the model was uploaded to the cloud and prepared for printing with a cloud slicer.
