World Flags Multi‑Color 3D Print Set

A set of 3D‑printable world flags, based on SVG flag sources and prepared for reliable multi‑color printing. Each flag is split into clean, stacked color layers so you can print vibrant, accurate flags with controlled color changes.

What’s included

• Flags for multiple countries, all normalized to a common 3:2 aspect ratio and uniform thickness (~3 mm).

• Separate STL files per color layer, with consistent alignment and registration for easy multi‑color prints.

• Variants where useful (e.g., simplified stripe patterns or cross patterns) to keep prints robust and slicing clean.

Printing tips (important)

• Highly recommended: enable Arachne (or your slicer’s equivalent “detect thin lines / contour printing” feature). This greatly improves the quality of narrow stripes, thin borders, and small details in many flags.

• I used a 0.4 mm nozzle and a moderate layer height (around 0.2 mm) for a good balance of detail and speed.

• For best color separation, treat each STL as a separate object / color in your slicer and allow color changes between layers.

Multi‑color plates (>4 colors)

Some flags require more than four colors on a single plate. For these models, I manually added pause commands in the G‑code during the print so the colors can be changed on a Snapmaker U1 without an AMS. When printing these plates, make sure your firmware supports the pause command and that you’re comfortable doing manual filament swaps mid‑print.
