2 colors fridge magnet with the Wow Horde logo uses 3x 5x2 mm neodymium magnets.
The gcode file already has a pause command during which you can insert the magnets and also a change filament pause. I used prusament jet black and prusament lipstick red.
I used 5x2 mm cylindrical magnets like these: https://hobby.shop.ro/index.php?route=product/product&product_id=21824
If you have other magnet sizes you can edit the Fusion file pretty easily.
I used 0.15 mm layer height for the red part, but I suspect 0.2mm will look mostly the same.
