A 3D‑printed phone holder featuring a dual-mode support—both upright and inverted, designed for versatile, multi‑scene use, including desktop movie watching, kitchen recipe browsing, and in‑vehicle navigation with inverted mounting. The holder adopts a hexagonal honeycomb lattice structure, with a bright blue main body and an integrated, foldable base and support arms that, when unfolded, form a stable triangular support system. The honeycomb design not only keeps the holder lightweight while enhancing structural rigidity but also ensures optimal airflow to prevent heat buildup on the back of the phone.

The holder supports 180° rotation: When used in the upright position, the tilt angle is approximately 60°–75°, ideal for everyday movie viewing; when used in the inverted mode (such as hanging in the kitchen or mounting upside down in a car), the support arms can be rotated to face the opposite direction, keeping the phone screen oriented upward to meet “inverted viewing” needs—whether it’s checking recipes in the kitchen or using in‑vehicle navigation with the screen mounted upside down. The non‑slip textured base, combined with a hollowed‑out design, maximizes friction to prevent slipping while also providing convenient cable management options (charging cables can easily pass through the hollowed areas). Round holes are strategically placed along the sides, allowing users to hang small accessories like earphones or keychains, further expanding the holder’s practicality.

Design Highlights

• Dual‑Mode Compatibility (Upright & Inverted): The support arms can be rotated 180°, enabling seamless one‑click switching between upright viewing and inverted use—for kitchen tasks or in‑car navigation—making it suitable for a wide range of applications.
• Honeycomb Lattice Structure: The hexagonal mechanical design evenly distributes pressure for more stable support; the hollowed‑out design reduces weight and accelerates heat dissipation, helping to prevent overheating of the phone.
• Foldable & Portable Design: The holder folds down into a compact, flat profile, making it easy to store and carry—perfect for tucking into a pocket or side bag, ready to go whenever you’re on the move for business trips or travel.
• Ergonomic Tilt Angle: With an upright tilt angle of around 60°–75°, the holder ensures a comfortable viewing angle even when used upside down, reducing neck strain.
• Anti‑Slip & Multi‑Functional Integration: The non‑slip texture on the base prevents sliding, while the side holes allow users to hang small items like earphones or keys—getting more out of a single accessory.

Technical Specifications

• Compatible Devices: Smartphones (width 58–85 mm, thickness ≤10 mm) and small tablets (7–8 inches)
• Recommended Materials: PLA (eco‑friendly, easy to print, available in a wide range of colors) and PETG (high temperature resistance and abrasion‑proof, ideal for long‑term use)
• Printing Recommendations: Use a 0.2 mm nozzle, set the infill to 20%–30% (balancing strength with lightweight design), and ensure the walls of the honeycomb cells are at least 1 mm thick to prevent breakage.
• Dimension Reference: When unfolded, the base measures approximately 80 mm × 50 mm with a height of about 100 mm; when folded, the holder is just 15 mm thick—perfect for compact storage.
