This is a round decorative coaster inspired by a armory emblem design.
The model is optimized for clean two-color printing and sharp logo contrast.

The coaster was printed using a manual filament swap (pause at layer) – no AMS required.
The result is a bold black & white finish with crisp raised lettering and emblem details.

Perfect as:

• Workshop or gun room decoration
• Desk coaster
• Display piece

The model has a slightly raised outer rim to help contain condensation from cold drinks.
