Coaster Set: Mathematical Geometry (Fractal, Moire, Op Art)

A set of 48 drink coasters in 6 collections of 8 made from mathematics: truchet tiles, nested forms, moire and guilloche, space-filling fractal curves (Hilbert, Peano, Gosper, dragon), fractal mandalas and optical-illusion grids. What is inside (6 collections x 8 coasters = 48 designs) - Truchet: Arcs, Double Arcs, Hex Loops, Loop Medallion, Arc Rosette, Double Crown, Loop Cross, Woven Star

- Nested Forms: Flower, Triangle, Square, Hexagon, Pentagon, Circle, Star Shells, Soft Pebble

- Moire: Sunburst, Lattice, Bloom, Snowflake, Lotus Cross, Woven Crown, Sixfold Bloom, Star Weave

- Fractal Paths: Hilbert, Gosper, Peano, Arrowhead, Dragon, Hilbert Compass, Gosper Bloom, Peano Cross

- Fractal Mandala: Hilbert Cross, Gosper Snowflake, Peano Star, Arrowhead Flower, Dragon Crystal, Moore Wheel, Gosper Trillium, Arrowhead Compass

- Optical Grids: Bulge, Twist, Polar Weave, Grid Compass, Woven Cross, Web Rosette, Lattice Star, Twisted Bloom

The coasters - 95 mm diameter, 4 mm thick, with an 8 mm centre hole and a flat underside.

- Two-tone design: a light coaster with the pattern standing out in a second, darker color.

No AMS needed. The coaster is a plain plate topped by the raised pattern, so two colors take a single filament swap: set a pause at Z = 3.6 mm (layer 18 at 0.20 mm layer height), the first layer of the pattern, then change the filament and resume.
