How are you making it magnetic?
- My guess would be magnets
  
  How do they work?
  
  Like a stick on magnet?
I'm saddened that I could not find that "It's a pentagram" -scene from the "Angels and demons" -movie. I hadn't really taken note of the fediverse -logo before this.
If you are up for suggestions. I would swap filaments at the layer after the base is finished and switch colors so that the logo will pop against the base color.
- Also add a few more top layers to hide the infill better.
- That's what I currently try (I am not OP) and it does not works. The slicers use one magic Gcode command (M600) that does all the filament change movements and interactions.
  My shitty printer (Weedo Tina2) does not recognize this command (I have found the documentation).
  A printer at my fablab (artillery X2) just ignores it.
  What do you use to make midprint filament change?
  
  You can also just pause it and change filament manually.
  Just remember to push through some of the filament until the color comming out is right.
  
  On my Prusa's there is a pause command. The Artillery should be using Marlin (unless you flashed something else). Your slicer (Cura especially) will let you add a pause and even tell the machine where to park the head, that doesn't use M600. I guess it depends on your firmware and the slicer you are using. It would easy to experiment with it. Put down a small test cube and add some pause commands and see what happens. I would use Cura or Prusa Slicer if you can as they both have pretty good support for the typical commands you would use on this.
  
  You can insert any custom GCode at any layer, at least with PrusaSlicer. So check what your printer supports for changing filament and try that.
Ah yea forget a important part there was a hole on the back where I was gonna put the magnet into so that’s what would make it a magnet
- When I make magnets on the printer. I create voids the shape of the magnet in the model near the bottom surface, then have the printer pause right before it the layer it is set to close the hole. Drop the magnets in and resume print. It will completely encase the magnet.
- I was going to say, other than that it looks pretty 'aight to me.
  You could just glue a disk magnet to the back, couldn't you? I have oodles of various souvenir magnets that are made by just hot gluing a cheap ferrite disk to whatever piece of bric-a-brac. I think that would be acceptable.
  It's not an un-magnet. It's a multipurpose medallion. Bring your own magnet, lapel pin clip, or Velcro.
- Yep. I've also seen it used for gift boxes that you have to break to open, you just insert the gift mid-print. Or recently for an unsolvable riddle: https://www.printables.com/cs/model/596644-unsolvable-riddle
Would be cool as a wax seal
