(Note: 3D-printed objects may require additional steps for food contact e.g. coating).
A small bowl colored in a pattern loosely resembling wood rings, designed from ground up for FDM printing at 100 % scale. For best results set a 0.45 mm extrusion width with a 0.4 mm nozzle.

It's gone through a few iterations:

The design:
What looks (or at least "is supposed to look") like solid structured material is actually a one-perimeter solid body in the primary color for strength, with a two-perimeter color shell on each side (slightly wider at the bottom rim to tolerate sanding).
The resulting internal geometry gets fairly complex. Fortunately, computers are good at this:

Printing:
If in doubt, set the extrusion multiplier slightly higher.
Supports are advised, as the overhang near the bottom starts from 90 degrees.
100 % infill avoids cavities in rim and bottom. 15 % gyroid were used in the test print.
Printing time: ~12h with ironing enabled (Core One + MMU, 0.2mm structural)
