secret box

A box that can only be opened with the magnetic key. Nothing is visible from the outside.
You need 2 screws M3 x 24 and 6 magnets: 2x Ø10 x 2; 2x Ø3 x 3; 2x 10 x 5 x 5.
The 2 small magnets repel the Ø10 and act like a spring. The strong rectangular magnets overcome the smaller magnetic force and attract the Ø10 discs - thus unlocking the box. The latches are mounted on the left and right so that the lock cannot be opened simply by tapping. It is important to pay attention to the polarity of the magnets, otherwise the opening and closing will not work.
