Tartan Pattern Coaster

This pattern was a request, I don't know much about tartan patterns, I copied the Clan Wallace pattern for this. 3 pieces to the model, they are labeled as the colors I used. The red and yellow can be subbed out, but the black piece has the shading in it, so I would stay with black filament for the black object. If you take the .stl files and slice on your own, make sure you have the box 'detect thin walls' checked, or half the pattern wont print. Filament used:Bambu Basic Black PLAInland Yellow
