Coasters builds matching drink-coaster sets with a decorative two-color face — honeycomb, sunburst, rings, stripes, a monogram, or your own uploaded artwork — plus a fitted caddy to stack them in. Pick the Shape and Size first; 90–100mm suits most glasses and mugs. Face Pattern chooses the second-color design and Motif Size scales it, while Set Size controls how many coasters export on one plate — the caddy sizes itself to the stack automatically. Print face-up so the pattern lands in the top layers: a single filament swap at the right layer gives the two-tone look without a multi-material printer. A clean, level first layer matters most here, since the flat base is what sits on the table.
