The business card case consists of 2 parts that can be printed separately. For the hinge you need 2 M4 x 20mm self-tapping screws and 2 round 8mm x 3mm neodymium magnets for the lock. The magnets are inserted into the pockets provided. To do this, insert a break at the top end of each pocket when slicing. Pay attention to the orientation of the magnets. After you have printed both parts, join them together and screw the two screws into the hinge until they are as tight as you want them to be.
