Here the best of two worlds. I really like the Bambu Scraper (see link below), and I would like to use magnets to place them on my Core One with labeling. I used round 6x3 magnets. 

I create the .3mf in the way that you can modify the Naming based on your needs as well you can change the shape for the magnets based on what do you have at home.

6x magnets for the holder

Happy Printing!
