This is a fridgmagnet in the shape of a 3d box. It has a strong neodymium magnet in the back which can hold pretty much any document. It can also doubles as a puzzle on your fridge, fun for kids.
I've included 2 cura gcodes which pauses at layer 15 to do a filament change for multicolor. One for PLA and one for PETG.
Enjoy!
