Magnetic levitator inside magnetic levitator

The way I used the arrangement of the permanent magnets allows the pen to "levitate" regardless of the direction of gravity. In addition, it became possible to install another pen inside the pen in the same way. Theoretically, nothing prevents increasing the number of pens inserted into each other and you get a set of magnetic levitating "matryoshkas".
In addition to the printed parts, you will need 2 regular ballpoint pen refill made of non-magnetic materials.
5 pieces. round magnets 8mm x 1.5mm, 5 pcs. magnets 12mm x 4mm (can be replaced by 10pcs 12mm x 2mm), magnetization direction is axial, you should choose magnets with the highest strength.
Plexiglass ring 170mm x 110mm x 2.7mm
Choose the settings for printing of pens so that the details are as light weight as possible.
The same poles of the magnet in the pen and in the holding magnets face each other, they work by repelling each other. The distance between the magnet of the small pen and the magnets holding it is 4 mm, it depends on the length of the ballpoint pen stem, which must be carefully cut, a more accurate selection may be required. For a large pen, this distance is 5 mm and it is set by the depth of cut in the Plexiglas ring. The ballpoint pen refill for the large pen should also be cut.
