Diameter of the bottom plate and top ring
Total height incl. bottom plate and ring
Staves
Number of vertical wall staves (6–36)
Visible gap between neighboring staves (0 = flush)
Stave width: 39.8mm — one centered tab per stave
Plate & ring
Rim of the bottom plate and ring outside the staves
Radial width of the top ring — must accommodate the slot ring

Material
Plywood 3–6 mm is ideal for round boxes
Cut width of your tool — contours are offset outward by kerf/2
Spacing between parts in the cut layout
Round Box Designer
Design a round box from a bottom plate, a top ring and vertical staves: the staves form a chord polygon around the inner circle and lock into the slot rings of plate and ring with tabs. Diameter, height, stave count, gap, ring width and plate overhang are freely adjustable – check everything in 2D and 3D and export the cut files.
Round shape from flat parts
Every part is cut flat: plate and ring with slot rings plus identical staves with tabs – the round shape emerges during assembly, no bending required.
Fully parametric
Diameter, height, stave count and gap, ring width and plate overhang are freely adjustable; stave width and tabs are calculated automatically – kerf compensation included.
2D, 3D & export
2D cut layout with dimensions, 3D preview of the assembled box, and SVG, DXF or PDF export for laser cutters and CNC routers.
Tips for round boxes
- Stave count: More staves make the box rounder: 16–24 is a good range for a box you hold in your hand. Fewer, wider staves give a more faceted look.
- Gap: A small gap between the staves lets light through and gives a lantern-like character; keep it minimal for a closed look.
- Assembly: Push all staves into the bottom plate first, then press the top ring on in one go – it aligns every stave at once. Glue only the tabs.
- Material: 3–4 mm plywood is ideal: the staves are narrow, so thicker material widens the slots and the polygon becomes coarser.
