[how to print ? need advice on support structure planning]

tried to print and indeed I need a support.

The question is what kind of support structure I need to design.

Do I need to add a vertical tube every 1 cm ? What diameter ? Same surface as the top surface or should I keep a distance ?

How can I learn of support design ?

Thx
