Segmented bowls

Work from the shop — the kind of piece a cut list has to be right for. One segment out of true and the ring will not close.

What the desktop version adds

The browser app draws the profile and gives you the ring cut list. The desktop version adds the segment-face pattern editor, multi-colour printing and Blender export.

Segmented Bowl Designer with a maple and ebony checkerboard bowl: half-profile editor, 3D preview and per-ring cut list
Draw the half-profile on the left — the 3D bowl and the full cut list build themselves. Maple and ebony, 20 segments a ring.
Looking straight down inside the 3D preview of the checkerboard bowl, showing how the segment pattern lands ring by ring
Tip the preview and look straight down inside — see every joint land before you glue a single ring.
A cherry and ebony brick-stagger bowl previewed in 3D beside its profile and cut list
Change the woods, the segment count, the stagger — cherry and ebony here, 24 segments a ring, recalculated live.

The inside tells the truth: stagger, joints and the solid base, checked from every angle before you cut.

Why $200?

Segmented-turning calculators start around $50, and they do one job well: the numbers for the lathe. Segmented Bowl Designer gives you those too — then takes the same design all the way to a finished, printable, glue-ready result.

Questions before you buy

Do I need to install anything?
The browser app runs in any modern web browser — nothing to install. The desktop version is a Windows download you activate with your order number.
What files can I export?
The browser app exports an STL for 3D printing and a CSV cut list. The desktop version adds colour 3MF for multi-filament printing, printable inlay pieces, a Blender (GLB) export, and true-size PDF cut guides.
Do I need to know CAD or 3D software?
No. You draw the half-profile and the app builds the 3D bowl, the ring stack and the full cut list for you.
Is the desktop version Windows only?
Yes — the desktop app is Windows. The browser version works on any computer.
Can I try it before I buy?
Yes. Draw and preview in your browser, and your first cut list is free. The $200 desktop licence is a one-time purchase.
Can I get a refund?
The desktop licence comes with a 30-day money-back guarantee, and unused cut-list credits are refundable within 30 days — see our Refund Policy.
