🌹 A Ring/Gift Box That Blooms
A mechanical blooming rose gift box designed to turn opening a gift into a moment.
When the lid is opened, a gear-driven mechanism causes the flower to bloom automatically, revealing the ring, note, or gift inside. The core blooming system is print-in-place, while the surrounding parts are modular and customizable.
Designed for Valentine’s Day, proposals, and special occasions — but built to stay useful long after.
⚙️ Gear-Driven Blooming Mechanism
- Print-in-place gear-driven blooming mechanism
- Smooth opening motion after a short break-in
- Carefully tuned tolerances for reliable FDM printing
- No supports required for the main mechanism
🌿 Modular & Customizable Design
The design is intentionally modular to encourage customization and reuse.
Interchangeable center attachments:
- 💍 Ring holder
- Includes multiple ring slot sizes to fit different ring dimensions
- 📦 Larger storage container
- 💌 Note holder
Leaves are assembled separately, allowing:
- Easy multi-color prints without AMS
- Reprinting or recoloring individual parts
- Material experimentation
💖 Functional Re-Use After the Gift
After the gift is given, an optional attachment can be added to the inside of the lid to convert the box into a jewelry organizer:
- Ring hanger
- Earring hanger
A Valentine’s gift that stays functional instead of being stored away.
🖨️ Printing Information (Important)
- Designed specifically for FDM printers
- The most critical part is the print-in-place joint mechanism
- Use PLA in good condition (preferably dried) for best results
- Ensure the build plate is clean for proper first-layer adhesion
- Leaf joints should move very easily without force
- Leaves include small, easy-to-remove supports
- Other parts are straightforward to print and can be printed in:
🔧 Assembly Notes (Please Read)
Step-by-step assembly instructions are provided as GIFs on the model page.
Key points to ensure reliable operation:
GIF 1 – Case & Gearbox Assembly
- Pull the rack fully upward before assembling the lid
- When assembling the lid:
- Push down on the joint
- Slide the filament pin into place
GIF 2 – Breaking In the Mechanism
- Break in the print-in-place slider joint by hand first
- Then break in the revolute leaf joints
- The slider may require some force
- Leaf joints should be able to rotate freely
GIF 3 – Assembling the Leaves
- Do not use excessive force
- Insert leaves parallel to the joint
- Take care not to overstress or twist the joints
- Make sure the leaves can fall on their own; if not, open and close the leaves until they fall freely
GIF 4 – Assembling Flower & Case
- Align the flower base slot with the protruding rack
- Press perpendicular to the base (some force may be required)
- After it clicks:
- Align the slots of the case and flower base
- Press them into the base until they snap in
GIF 5 – Attaching Center & Closing the Flower
- Close the leaves simultaneously
- The leaves should naturally align as they close
- While keeping the leaves closed, lower the lid
- Continue gently closing the leaves so the inner petals are guided inward
- This ensures proper alignment and reliable blooming
❤️ Final Notes
This design combines motion, modularity, and emotional impact into a single print.
If you like the design, a ⭐ or ❤️ really helps — especially during the Valentine’s contest!
Happy printing 🌹
