This is a beautiful and elegant butterfly magnet design for your fridge that can be printed in multiple colors. There are 3 slots for 5mm x 3mm magnets on the back. There is also a variant with no magnet holes if you want to hang it up in a different way or use it as a coaster. This is an easy print with no supports required.

There are several files included. There is a .3mf file for Bambu Lab users with an AMS, which uses the butterfly-magnet STL. There is also a butterfly-nomagnet variant that does not have holes for magnets.

If you don't have a multi color printer, you can use the butterfly-layer-change file which has a different height offset for the orange and white areas so you can color swap between layers. You start the print with orange, then swap to white for a few layers, then to black.
