🔐 Puzzle Box – Secret Mechanism – Interchangeable Panels

A mysterious 3D-printed puzzle box featuring an invisible internal mechanism based on a moving double floor, magnets, and a hidden steel ball.

📦 Main Features

• Built-in secret mechanism (magnets + sliding floor + hidden ball)
• Automatic lid lift when the box is unlocked
• Decorative panels interchangeable (or permanently glued, your choice)
• “False-lead” effect: panels look like they hide the solution, enhancing the mystery
• Easy 3D printing – all parts assemble without screws
• Fully customizable (themes, colors, difficulty levels…)

📏 Dimensions

Complete box: 200 × 140 × 95 mm

Interchangeable panels:

• Top: 186 × 125 mm
• Front / Back: 172 × 54 mm
• Sides: 110 × 54 mm

🧲 Magnets used

• 4 × 10×3 mm magnets in the false bottom – Part 2
• 8 × 10×3 mm magnets under the lid (4 attraction + 4 repulsion)
• Side panels: 5×2 mm magnets
• Top panel: 6×2 mm magnets

🎭 Decorative Panels

Two mounting options:

1. Glued panels

Simple and permanent solution.
Perfect if you don’t need to change the theme.

2. Magnetic panels

Panels can be swapped at any time without tools.

False-lead effect:
Because the panels are lightly held by magnets, the user may think they hide a button or locking system — this intentional illusion strengthens the puzzle experience.

🧩 How the puzzle works

• A steel ball must fall into the correct spot inside the double floor — blindly.
• The position of the floor changes the alignment of the magnets (attraction ↔ repulsion).
• When the correct alignment is reached → the lid gently lifts open by itself.

🎨 Available Themes

• Vinci theme (included)

More themes will be added based on community interest:
Christmas, pirate, jewelry, mechanical, magic, and more.
