The design is inspired by the traditional Chinese Linglong Ball.

A nested sphere with a diameter of approximately 56 mm, designed for testing PVA water-soluble supports.

It is recommended to print this model using an X2D or H Series printer. 

Please dry the support material in advance according to the instructions provided in the wiki.

When printed with standard support settings, the model uses approximately 58 g of PVA.

The PVA water-soluble support can be dissolved by soaking it in warm water for approximately half a day.

The final image shows the top surface quality, allowing you to compare the print quality of unsupported surfaces with the interface printed against the water-soluble support.
