Let me introduce the highly customizable lamp shade.
You can create a cone, cylinder, cube, sphere, pyramid, star, flower and a dodecahedron shape. These are only the shapes I could find, but there are much more shapes to discover.
You can customize different sizes and the hole for the bulb bracket.
You can create a lamp shade as a ceiling lamp or a desk lamp or for a different purpose like a nice bowl or a vase.
You can view some examples in the pictures above.
