Description
This Christmas Surprise Box delivers a festive reveal in one simple pull.
Lift the ribbon on the lid, and the four side panels spring open under rubber-band tension while Santa pops up from the base, instantly turning a small gift box into a joyful holiday moment.
Designed for easy printing and assembly, this model uses smart mechanical details to keep the build simple while maximizing the surprise effect. It works great as a Christmas decoration, a desk display, or a fun gift box for kids and friends.
Key Features
- No extra hardware required
All hinge joints are assembled using filament as pins. No metal rods or special parts needed. - Powered by just two rubber bands
The entire opening and pop-up action is driven by only two rubber bands, keeping the mechanism simple, reliable, and easy to assemble. - Smooth flipping with minimal tuning
If any joint feels tight due to print shrinkage, lightly sanding the hinge area with #400–600 sandpaper will allow the panels to flip smoothly. - Flexible Santa attachment
The Santa figure includes a round hole under the feet for mounting with filament.
If the fit is not secure enough, you can reinforce it using glue or an M2.2 × 10 self-tapping screw. - Two printing configurations included
Optimized profiles are provided for both AMS and non-AMS setups, allowing fast and convenient printing on different machines. - Easy to paint and customize
Santa can be printed as a plain white model and colored using acrylic markers or paint. This makes customization simple and adds a warm, handmade look to the final result.
Printing Notes
- PLA is recommended for easy printing and smooth movement
- Use rubber bands with moderate tension for the best opening speed
- Light sanding on moving parts is normal for mechanical prints
