Magnet Polarity Identifier, only 0.4g of filament required

A polarity identifier requiring only 0.4g of filament, which can adhere to the side of a P1S if the magnets are sufficiently strong, for convenient access.
The animation demonstrates that the magnets remain secure without any adhesive, unless another magnet is used to attract them.

If adhesive is used, exercise extreme caution to avoid contact with skin due to the small size of the component.

Two 6mm diameter, 3mm thick magnets are employed.
