To Print:
If slicing yourself, rotate it to be as shown in the print pictures.
I recommend printing with PETG, and using a tiny drop of super glue before inserting the magnets so they don't rattle.
You'll want to put some supports in the inside to support the top of the hole, I like using 24 degree overhang paint on supports in PrusaSlicer.
Add two color changes right as the holes for the magnets get covered and place the magnets in there when it pauses and continue.
