Hidden Compartment Puck –Magnetic Secret Mechanism

Bill of Materials
Description
At first glance, this is just a puck—clean, minimal, and unassuming.
Beneath the surface, however, is a hidden mechanism that only reveals itself when aligned correctly.
The lid is held by friction and won’t open by force.
Instead, a precise rotation activates two press-fit 3×6 mm magnets that repel each other, overcoming the friction and releasing a hidden compartment.
The motion isn’t obvious at first, but quickly becomes intuitive and deeply satisfying. To anyone who doesn’t know the trick, the puck stays closed—making it a discreet and clever hiding place. A small secret, hidden in plain sight.
Print & Assembly Notes
- Designed for friction fit – tolerances may vary slightly depending on printer and material
- Uses two 3×6 mm magnets, press-fit (no glue required)
- Orientation and magnet polarity are critical for proper function
- Best printed in PLA or PETG
