In designing a cup for my journaling pens/pencils I decided on a conical shape but wanted some internal dividers. Being unskilled with Fusion 360 I was fussing how to get the dividers to work out. I turned to a Kagi search and on the first result discovered Fusion has a "Web" tool which auto-magically did exactly what I wanted.
The result: https://www.printables.com/model/1080103-conical-penpencil-cup-with-internal-dividers
