This is my first design, I made it for work.
It takes 3 x 6x2mm magnets
Make sure to print outer walls first, then the magnets should press fit, though I glued mine to be sure
I added the text in the slicer, but left it off the main print to allow for customization and easy printing on the top face without supports.
