Summary Miserably failing magnet. Put it on your fridge, door, broken car, printer or your ex-boyfriend's picture .. what NOT can you use it for?! Possible as a two colour print with a filament swap. The letters have a hole in the back that fits a magnet with a diameter of 12mm and a thickness of 3mm, which I happened to have lying around. Post-Printing Do a filament swap at z-height 4mm to get a nice two colour magnet. For the rest it's a very simple and easy print. To add the magnet, adding a dash of glue is recommended.
