Super yummi Oreo magnets! Insert the 3 magnets (6x3 or 6x2 mm) in the slots on the back and place them where ever you want!
I printed mine for the office whiteboard :)
Show me yours!
Printed with Bambu PLA and AMS. But you can also simply add a pause at the color switch in Bambu Studio and change the filament manually. I didn't need any glue for the magnets as they sit very tight but depending on your tolerances and filament.
