A simple satisfying clicky toy, spin the buton around the circle and feel it snap onto magnets with a pleasant, audible click.
Use 8*3mm magnets.
When printing, set up a pause right before the layer covers the magnet hole on both items, insert the magnets and resume the print. make sure that all the magnets face the same direction. It's doesn't matter whether it's south or north, as long as it's the same orientation on all the magnets.
the bambu 3mf file has the pauses set up in correct spot.
have fun!
