Capture the romantic sea breeze of Qingdao in your hands! This model is inspired by “The Wind of May,” the iconic urban sculpture at Qingdao’s May Fourth Square, and was created based on this masterpiece. Unlike traditional static models, the standout feature of this piece is its ingenious incorporation of a hidden hinge mechanism. When folded up, it presents as a flat puzzle just 1 cm thick; once unfolded via the built-in hinges, the layered red structure instantly transforms into that classic “burning flame,” delivering a striking visual impact and endless fun to play with.

A lanyard hole is conveniently预留ed at the top, making it perfect whether you use it as a portable keychain or backpack charm, or display it on your desk as a stress-relieving little decorative item.

✨ Design Highlights

• Integrated, Assembly-Free (Print-in-Place): The hidden hinge design eliminates the need for screws or post-print assembly—everything is printed in one go, and you can start playing with it straight off the heated bed.
• Sleek and Portable: When folded, it’s ultra-flat and compact, taking up minimal space while perfectly replicating the sculpture’s silhouette.
• Smooth, Seamless Unfolding: Precisely calculated hinge tolerances ensure smooth rotation between layers (we recommend calibrating filament flow before printing to prevent sticking).

📏 Specifications and Cost Parameters

• Model Dimensions: 10 cm × 10 cm × 1 cm (length × width × thickness)
• Estimated Weight/Printing Material Cost: Exceptionally cost-effective, with material costs of approximately 15 yuan per print.

⚙️ Printing Recommendations

• Recommended Filament: PLA or PETG (strongly recommended: use bright red filament to faithfully reproduce the sculptural texture of “The Wind of May”)
• Slice Layer Height: 0.2 mm
• Filling Density: 15%–20%
• Support Settings: No supports required (ensure strong first-layer adhesion)
• Printing Tips: Since the model includes hidden hinges, if your printer tends to exhibit severe “elephant foot” (first-layer edge extrusion), we recommend enabling “first-layer XY compensation/elephant foot correction” in your slicing software to prevent the hinge base from sticking and failing to rotate.

🎁 Suitable Applications

• DIY souvenirs for city travel
• 3D-printing enthusiast gatherings and showcasing skills
• Creative stress-relief toys
• Gifting to friends who love Qingdao
