This is a 3D‑printed, one-piece Chinese-style octagonal star–patterned hollow window-cut coaster, crafted entirely from vibrant, festive, matte, eco‑friendly filament in a rich rose red. Drawing inspiration from traditional Chinese eight-pointed stars, knot‑tied motifs, and geometric floral patterns, it seamlessly blends intangible cultural heritage paper cutting with modern hollow‑carving techniques—resulting in a miniature window-cut coaster that combines celebratory decoration, practical heat insulation, and timeless Chinese aesthetic appeal.

The overall design features a symmetrical, standard octagonal star shape, with evenly radiating, pointed petals that converge toward the center, forming a small circular aperture. The entire surface is intricately woven with hollowed-out textures, adhering to the Chinese compositional aesthetic of “eight directions of completeness and harmonious symmetry.” The edges are meticulously rounded and softened, eliminating sharp corners for a smooth, non‑abrasive feel that won’t scratch your tabletop.

In terms of pattern detail, the interior is densely adorned with interlacing, knot‑like hollow carvings, where lines are uniformly thick yet delicately balanced. The warp and weft intersect to form continuous, auspicious knot patterns, symbolizing “unending prosperity and enduring good fortune.” The eight petal tips extend outward, each ending in a rounded bead to reinforce the hollow structure and prevent breakage. The openwork gaps are evenly spaced and perfectly translucent; when light passes through, the resulting layers create a rich, nuanced depth—capturing both the delicate finesse of paper cutting and the textured, organic feel of woven craftsmanship.

Manufactured using high‑precision FDM 3D printing, this piece is seamlessly integrated without any joins, ensuring fine, unbroken lines and naturally subtle layering. The matte red finish boasts a deep, velvety texture that exudes warmth and festivity without being overly bright or harsh on the eyes. The material is environmentally friendly, rigid yet durable, offering excellent heat insulation and anti‑slip performance—making it ideal not only as a heat‑resistant coaster for teacups, coffee cups, or aroma diffusers, but also as a New Year’s window decoration, hanging ornament, or decorative accent. The bold red hue pairs beautifully with Spring Festival celebrations, wedding ceremonies, and housewarming festivities, evoking themes of prosperity from all directions, versatile charm, family reunion, and year‑round peace and well‑being. Its compact, refined form is brimming with traditional Chinese charm and seasonal flair.

Second Design: Ginkgo Leaf Hollow Decoration/Cup Coaster (Rose Red 3D‑Printed Version)

This is a 3D‑printed, three‑dimensional ginkgo leaf–shaped hollow coaster—a petite desktop accent piece—crafted in the same festive rose red, featuring a matte finish. It combines biomimetic ginkgo leaf elements with an intricate, wicker‑style hollow-carving design, presenting a unified, sculptural form complete with a round base. Whether used as a cup coaster, aroma diffuser tray, or standalone Chinese‑inspired Zen decor, this piece effortlessly marries practical functionality with artistic elegance—making it a truly unique cultural and creative product.

The entire piece is printed in one seamless, integrated form, comprising three distinct components: a three‑dimensional ginkgo leaf fan, slender branch stems, and a round, intricately carved base. The ginkgo leaf faithfully captures its real‑world, fan‑shaped silhouette, with softly rounded, undulating leaf margins. The inner leaf surface is rendered as a diamond‑mesh lattice, meticulously hollowed out with fine, transparent lines that mimic the natural flow of leaf veins—light, airy, and far from heavy or cumbersome. The branches are slender yet sturdy, providing solid support to keep the leaf canopy upright and unyielding, while maintaining a graceful, suspended form that offers a sense of depth and dimensionality far beyond that of a flat coaster.

The base is a round, flat platform, its surface adorned with a circular lace‑like hollow pattern that echoes the leaf’s woven texture. Designed with a wider, thicker profile, it sits stably on surfaces without tipping over, while its smooth edges ensure secure, non‑slip placement for cups, aroma diffusers, or small decorative accents—and delivers exceptional heat insulation.

The entire piece boasts a matte rose red finish, richly saturated and full of festive vibrancy. The 3D printing process is executed with meticulous precision, yielding smooth, burr‑free hollow lines and a robust, long‑lasting material that resists deformation. In traditional Chinese culture, the ginkgo tree symbolizes longevity, auspiciousness, eternity, and happiness; its fan‑shaped leaves embody “family reunion and perfect harmony,” while the color red signifies prosperity and smooth sailing. This piece can serve as a cup coaster, aroma diffuser base, or jewelry holder—but it also shines as a mini desktop accent, a New Year’s decoration, or a charming wedding vignette. With its blend of Neo‑Chinese Zen aesthetics and celebratory ambiance, it exudes a refined, understated elegance that feels both niche and sophisticated.

Overall Summary of the Set

This red‑toned hollow‑carving collection strikes a perfect balance between solemn, festive grandeur and deeply rooted Chinese cultural flair. The octagonal star motif is dignified and celebratory, steeped in traditional Chinese style; the ginkgo leaf, meanwhile, is three‑dimensional, lively, and subtly elegant, imbued with a gentle Zen spirit. One piece is still and contemplative; the other is dynamic and upright—both brought to life through 3D hollow‑carving techniques, united by a cohesive red palette that conveys auspiciousness, wholeness, and enduring blessings. Whether used as a practical heat‑resistant coaster or as a mood‑setting New Year’s/wedding decoration, this set is a thoughtful, finely crafted addition to any home, tea table, or gift-giving occasion—offering a touch of artisanal quality and cultural richness in every detail.
