Choose the type : Cylinder, Hex, Square, Octagonal, Oval, Rectangle, Rectangle with Bevel, Heart. Choose the axis type you prefer: Hex, Square, Cylinder. You can also chose the cap: Cube or Sphere.

If you are having any difficulties, need advices or you want me to make changes, I remain at your disposal.
