This is a magnetic closure protective case for the Playdate game console, emulating the look of the official case (which sells for $30!) Print in PLA at 0.3mm or finer resolution. Any infill you want, I think I used 12-15% or so.

The hinge is "live," meaning that the plastic bends to create a hinge. After removing the print from the bed, simply fold the case both ways several times to loosen up the plastic.

The magnets used are 6mm diameter 3mm height "rare earth" magnets. Search Amazon for "B07873ZCY4" for one such product, but any 6x3mm magnet should do the trick.

Because of the "lip" around the edge of the base, you may need to stack two magnets on top of one another and use pliers to press them into the hole, then you can remove the top magnet.
