This is a small case to hide your key under something magnetic. 

To print this model, use 0.15 mm layers (initial and subsequent) for the bottom part (KEHI01-0002). Program a pause at height 3.3 mm to insert 10 mm diameter x 3 mm thick magnet. Secure with glue before continuing the print so that the magnets don't come flying at your hot end when it comes too close.
