How to open

Hold the box horizontally in front of you with the small notch of the lid facing you. Open the lid until resistance sets in. Now tilt the box to one side by 45 degrees, shake it a little and gently continue pulling on the lid (be careful, too much force will block the mechanism). When the lid has opened further, tilt the box 45 degrees to the other side and repeat the previous step. You should now be able to open the box.

Bill of Materials

• box (1x)
• disc (2x)
• lid (1x)
• wall (1x)
• washer (3x)

Assembly

Place on the wall's pin: washer - disc - washer - disc - washer. Make sure that the two discs have different orientations, otherwise the puzzle becomes too easy. Next, force the wall into the box's notchs. If anything goes wrong, the wall can be removed again with a screwdriver or similar tool (leverage effect). Finally close the box with the lid. At the beginning, the closure may be a little too tight. If so, close and open the lid several times until the closure is less tight.
