This magnetic slider fidget has a satisfying feel and makes a satisfying click at each position! Simply wait for the pause that's included in the print profile, then insert the magents. I would recommend matching the polarity for all placed magnets (i.e. all positive facing the build plate) for simplicity sake. The most critical is that the cradle or larger piece of the print has matching polarity (i.e. positive facing up for both magnets). Then resume the print and let it cool! 

For easy multi color, just print my other magnetic slider in a different color! They are cross compatible so the two and three position parts can be swapped.
