1. The model is pre-designed with precise mounting slots for four D4×2 cylindrical magnets and includes a built-in pause function; be sure to insert the magnets during the pause. When the print reaches the layer corresponding to the magnet slots, pause the printer, embed the appropriate magnets, and then resume printing. 2. When embedding the magnets, pay close attention to their magnetic polarity: the three magnets inside the lampshade and the one on top of the ghost (the larger number is used to achieve the levitation effect; alternatively, stronger magnets can be used to reduce the total number required) must be oriented so that opposite poles attract. Installing them in the wrong orientation will prevent proper magnetic attraction and suspension.
