Magic Safe

This is a magic safe.
Requires 3 D10*2MM round magnets
Plate 1 is the outer frame
Plate 2 is the first layer box and its matching lid
Plate 3 is the base of the entire model, requiring two D10*2MM round magnets
Plate 4 is the second layer box and its matching lid, requiring one D10*2MM round magnet
Note: Plate 4 has a pause setting (at a height of 3MM) at this point you can embed the D10*2MM round magnet

Assembly method
1. First, insert the first layer box into the outer frame (only one side can be inserted, and it can be opened from the other side)
Then glue the matching lid to the first layer box (it must be inserted first and then glued, otherwise it will not be able to be inserted later)
2. The second layer box and the matching lid can be glued together first
3. The base consists of three parts (A, B, C from small to large). Take out model A and insert two round magnets into the two round holes (the two polarities should be opposite: for example, one N pole is upward and the other is S pole upward). Then place model A into the middle of model B, and then glue B and C along the recesses.
4. Insert the second layer box into the first layer box with the magnet end facing the base (insertion point)
5. Glue the base on

Gameplay: Use tapping to make the model A in the base move left and right, creating different polarities to control whether the second layer box pops out or stays inside the box.
You can also use other magnets to attract the magnet of model A at the bottom to move it left and right
