Dungeons & Dragons D20 coaster

Roll a nat 20 every time with this bold D20-themed coaster! Designed to look like a classic 20-sided die, this multi-color print makes a perfect addition to any tabletop gaming setup. Whether you're a D&D dungeon master or a casual dice goblin, it's a great conversation starter and a practical way to keep your table safe from drink rings. This version was printed on a Bambu A1 mini using AMS multi-color printing, but it’s also great for filament swaps or post-processing if printed in a single color. Sized to fit standard cups/mugs. No supports needed. Recommended settings: 0.2mm layer height, 3 walls, 15–20% infill (grid or gyroid). STL is flat and should be ready to slice as-is.Easily remix the color scheme or swap the number faces for themed variations (critical fail coaster, anyone?).
