Mandala Coasters — 5 Geometric Patterns (92mm)

Five geometric mandala coasters, 92 mm diameter, 4 mm thick. Each coaster is an open strut pattern — the mandala itself IS the coaster, no solid disc underneath. Prints flat, no supports, single color. **The five patterns:** - `coaster_1.stl` — Sun wheel (24 radial spokes + 3 rings) - `coaster_2.stl` — Lotus (12 teardrop petals + double ring) - `coaster_3.stl` — Star lattice (Star of David + overlapping squares + hex) - `coaster_4.stl` — Rosace (gothic rose window, 6+6 petals) - `coaster_5.stl` — Ornate (36 fine spokes + 8-point star) Print any single pattern or all five as a matched set. Outer rim is solid (4 mm wide) so the coaster holds shape; everything inside is open strut so hot / wet glasses drain straight through and don't stick.
