In order to store the scalpel I designed a box with a magnet on the top and the bottom in order to close properly. Filament (1.75 mm) is used for the joint in the back with a 150 mm long piece. The magnet on the bottom half is glued in place. The magnet in the top part is inserted while printing (At layer heigt 2.7 mm). Check polarity before using the glue!
