Arc Desk Organizer

About this project

A three-cup desk organizer with stepped heights - tall for pens, middle for markers and scissors, short for clips and odds and ends. Each cup has soft vertical flutes outside and a smooth round bore inside, and all three stand on one shared rounded base.

How it's built

  • Cups - each cup is a fluted equation-curve profile extruded to its own height, with a smooth cylinder cut out above the floor. Flutes only add material outward, so the wall is measured at the flute valleys.
  • Spacing - cup centres follow the diameter and flute depth, keeping a 2 mm gap between neighbouring cups at any size.
  • Base - a rounded plinth under all three cups ties them into one part.
