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.
