We considered the general form of this lampshade as a four-sided cone, which according to the requested dimensions, we placed the largest opening at the bottom of the lamp, and the closer we get to the top and the head of the lamp, the smaller the proportions become.

To increase the optical luxury, we considered the following:

1. Creating a conical shape to open the light
2. Use of translucent materials
3. Making holes in the wall of the lamp

Lines and divisions on the lamp wall are done parametrically.
